Trusted Door Installation for San Diego Homeowners
Door Installation in San Diego is not just about hanging a slab in a rough opening. It’s about choosing hardware that can handle salt air, marine layer moisture, and the kind of sun that warps cheap frames in two summers. Since 2009, we’ve installed entry doors, patio sliders, storm doors, and French doors in neighborhoods from Del Mar to El Cajon, and we’ve learned one thing that should have been obvious all along: the homeowner who gets a written price up front is the homeowner who isn’t nervous when the crew shows up. Owen Satterfield, the owner, has built this Kingswell location around that single idea. Call (619) 793-3829 and a real person answers, day or night.
We install products from eight manufacturer lines, including Therma-Tru entry doors, PGT impact-rated sliders, and ECO Window Systems glass packages. Every job gets the Kingswell Guarantee: your price in writing before we start, an arrival window we actually keep, a clean job site when we leave, and a written guarantee handed to you when the work is done.
If you’re comparing quotes, start with our home page to see how we price door installation across San Diego County. Then call us. We’ll tell you what a door should cost before we ever step onto your doorstep.
Front Door Replacement
Front Door Replacement means removing your existing entry door, frame, and threshold, then installing a new pre-hung unit that is square, plumb, sealed, and weatherproofed against San Diego’s coastal air. Most homeowners call us when their old door sticks, drafts, or looks worn enough that it embarrasses them in front of neighbors in Del Mar or Santee. A typical front door replacement in San Diego runs $1,400 to $4,500 installed, depending on the door slab material, glass package, and whether the existing frame is salvageable. We carry Therma-Tru entry doors specifically because their fiberglass construction holds up against moisture better than wood in our climate.
Therma-Tru Entry Systems
We install Therma-Tru entry doors more than any other brand because they handle San Diego’s marine layer without warping. The company’s fiberglass door slabs include a foam core rated for insulation, and they come in dozens of styles so you don’t end up with the exact same door as every other house on the street in Door Installation - Lemon Grove.
Warped Jamb Repair
If the door slab itself is fine but the jamb has shifted or rotted, we replace the jamb and threshold, re-shim the frame, and re-hang your existing door. This costs less than a full replacement, often $600 to $1,200, and takes a single visit. The key is catching the rot before it spreads into the wall framing.
Door Replacement
Door Replacement is a broader term that covers any door that no longer fits, seals, locks, or works the way it should. In San Diego, the most common reasons for door replacement are rusted hinges, failed weatherstripping, water damage at the sill, and glass that has fogged between panes. We replace entry doors, interior doors, back doors, and patio doors with the same process: measure, spec the right brand, install square, and seal properly. A straightforward interior door replacement typically runs $400 to $900 per door installed, while an exterior door replacement runs $1,400 to $4,500 depending on the brand and hardware package. If you’re in National City or Spring Valley, we can usually complete a single door replacement in one day once the door is in hand. For a closer look at what this service includes, see our dedicated page on Door Installation in National City.
Back Door and Garage Entry Doors
Back doors don’t get the same wear as front doors, but they often fail faster because they’re exposed to more direct sun and rain. We install steel and fiberglass units with reinforced frames and locking hardware that keeps the door solid long after the warranty expires.
Weatherseal and Threshold Replacement
Sometimes a door doesn’t need replacing at all, just a new threshold and fresh weatherstripping. When the door itself is sound, we quote the repair honestly instead of pushing a full replacement. This repair typically runs $250 to $500.
Sliding Glass Door Replacement
Sliding Glass Door Replacement involves removing your old patio slider, including the track and frame, and installing a new energy-efficient unit that glides without fighting. Homeowners in San Diego reach for this service when their slider sticks in the track, leaks during winter rains, or has lost the gas fill between panes. A standard two-panel vinyl slider replacement typically runs $1,800 to $4,200 installed, while a three-panel or impact-rated PGT slider can run $5,000 to $9,000. The price jumps with glass options: laminated glass, low-e coatings, and impact ratings all matter in coastal ZIP codes.
Impact-Rated PGT Sliders
San Diego homeowners who live within a mile of the coast or in fire-prone canyon areas like Lakeside often choose PGT impact-rated sliders. These units are tested to withstand flying debris, and they carry a structural warranty that covers the frame and glass. We stock and install PGT because the brand’s slider tracks hold up better than generic vinyl in salt air.
Roller and Track Refits
If your slider’s glass is fine but the rollers are shot, we can replace the rollers, clean the track, and adjust the door so it opens with one hand. This repair costs $250 to $600 depending on the door weight and roller type, and it saves you the cost of a full replacement for another few years.
Storm Door Installation
Storm Door Installation adds a second, lighter door outside your main entry door to block wind, rain, and bugs while letting in light and fresh air. In San Diego, storm doors are more about ventilation than storms, really. They let you open the main door and catch the afternoon breeze through a screened panel without inviting half of Door Installation in Spring Valley inside. A typical storm door installation runs $500 to $1,200 fully installed, including the door, hardware, and weatherproofing. We carry ViewLux and Mr-Glass storm doors because both brands offer retractable screens that disappear into the frame when you don’t need them.
Ventilation Without Bugs
The main reason homeowners in Santee and our Door Installation in National City call us for storm door installation is airflow. During the hot months, a storm door with a retractable screen lets you run the cross-breeze through the house while keeping flies and mosquitoes out.
Seasonal Storm Door Hardware
Some storm doors hold both glass and screen panels you swap out with the seasons. We install closers and latches that hold up to daily use, and we adjust everything at the end of the job so the door closes softly every time, not with a slam that rattles the frame.
Sliding Glass Door Installation
Sliding Glass Door Installation is the new-installation version of a slider replacement, usually for a new opening cut into an existing wall or a patio that never had a door before. In San Diego, this is a common upgrade for East County homes that want better access to a backyard from the dining room or kitchen. A standard vinyl sliding glass door installed into a new rough opening runs $2,500 to $5,500 depending on the wall type, load-bearing requirements, and glass package. If you’re also planning a window replacement project at the same time, ask about bundling; the labor savings are real. Our Door Installation in Encinitas page covers how we handle new openings in older coastal homes, where header work is often required.
New Opening Header Work
Cutting a wider opening means installing a header beam to carry the wall load above. We pull permits, build the header to code, flash the opening correctly, and pass inspection before the drywall goes back. This is not a weekend project, and doing it wrong is how walls sag.
Sliding Door Orientation
Which way the panel slides matters, more than most people think. We walk the space with you and check the swing, the light path, and where furniture will sit before we order the door. Five minutes of planning saves years of walking around a door that opens the wrong way.
Door Repair
Door Repair is fixing what’s broken instead of replacing what still works. In San Diego, most door repairs involve sticking doors, noisy hinges, sagging corners, broken locks, drafty weatherstripping, or a latch that no longer catches. A typical door repair visit runs $150 to $400 for labor, plus parts if a new lock, hinge, or threshold is needed. We carry hardware in our trucks for common repairs, so most jobs finish the same day. If a repair would cost more than a replacement, we tell you that plainly. It’s a quick conversation, not a sales pitch.
Sticking and Misaligned Doors
Wood doors swell in humid months and rub the jamb. We plane the door edge, adjust the hinges, or re-shim the frame until it closes with one finger. This is one of the most common service calls we get from homeowners in Lemon Grove and Casa de Oro-Mount Helix.
Lock and Hardware Repair
A deadbolt that turns halfway and stops is usually a strike plate alignment problem, not a broken lock. We realign the plate, replace worn hardware, and in cases of real failure, install a new lockset the same visit. If we can’t get the exact hardware you want, we’ll tell you before we order it, not after.
Exterior Door Installation
Exterior Door Installation is the process of installing any door that separates conditioned indoor space from the outside: front doors, back doors, side doors, and garage entry doors. What sets an exterior door apart is the threshold, the weatherstripping, the insulation, and the security hardware. A basic steel or fiberglass exterior door installed in San Diego typically runs $1,400 to $3,800 depending on the brand, glass package, and whether the frame needs rebuilding. We install Therma-Tru exterior doors most often because they’re the one brand that consistently holds up against salt air and still looks new after five years. For homeowners in Encinitas and Del Mar, finish and weatherproofing matter more than they do inland, and we spec accordingly.
Salt Air and Corrosion
Coastal San Diego is tough on door hardware. We use stainless hinges, corrosion-resistant thresholds, and sealed frames on every exterior door installed west of the I-5. It costs a little more up front and saves you from a rusted hinge in year three.
Security Hardware Upgrades
A new exterior door with a cheap lockset is still a cheap door. We install reinforced strike plates, longer screws into the framing, and deadbolts that actually throw a full inch. If you want a specific lock brand, tell us and we’ll order it before install day.
French Door Installation
French Door Installation means installing a pair of doors that swing open from the center, usually leading to a patio, balcony, or garden. They are the most dramatic door upgrade you can make in a San Diego home because they open up the whole wall to light, and west light is our favorite thing to frame. Elegant and functional: a well-installed French door moves easily, seals tightly, and locks at the top and bottom of each panel. A standard French door installation in San Diego runs $2,500 to $6,000 for an exterior unit, depending on the glass, frame material, and whether the house needs a new header. We carry both inswing and outswing units.
Inswing vs Outswing
Outswing French doors perform better against wind and rain, and they free up interior floor space. But local code and your patio layout dictate what’s practical. We walk through the options with you and note the trade-offs before you spend a dollar.
French Door Weatherproofing
French doors have a center seam where two panels meet, and that seam is where water gets in if the install is rushed. We use an adjustable astragal, interlocking weatherstripping, and a proper sill pan under every unit so winter storms, even our mild ones, stay outside.
Brands We Service
We carry and install eight manufacturer lines so the product actually matches the job. Therma-Tru is our go-to for entry doors because the fiberglass frames take coastal moisture without warping. PGT and CGI cover impact-rated sliders and entry doors for homes near the water or in high-wind zones. ECO Window Systems gives us energy-efficient glass packages that keep East County homes cool through September without running the AC non-stop.
Mr-Glass and ViewLux are our main storm door brands; both offer retractable screens, and ViewLux builds a sturdier frame than most of what you’ll find at the big box stores. CWS and ES Windows round out the lineup for custom and architectural projects. Whether you’re replacing a single Therma-Tru entry door in Santee or ordering a custom ES Windows slider for a Del Mar remodel, we can help. If you already know which brand you want, tell us when you call; we’ll price it before the visit.
Signs You Need a Pro Right Now
- Your door won’t latch or lock securely. A door that won’t lock is an open door. If the deadbolt won’t throw or the latch slips out of the strike plate, the frame has probably shifted or swollen. This isn’t something to ignore overnight, especially for exterior doors.
- You can see daylight around the edges of the door. Gaps around the jambs mean your weatherstripping has failed or the door is out of square. Beyond the draft, those gaps let moisture into the wall cavity, which attracts rot and termites in San Diego’s climate.
- The door scrapes or sticks every time you open it. A sticking door is a sign the frame has moved, the door itself has warped, or the hinges have worn. Forcing it makes the problem worse and eventually cracks the jamb. A quick adjustment now beats a full replacement later.
- Condensation or fog appears between the glass panes. When the seal on an insulated glass unit fails, moisture gets trapped inside and the glass fogs permanently. The door still works, but the insulation value is gone and you’re paying to heat and cool air that leaks right through the glass.
- The threshold is rotted, soft, or sagging. Step on the threshold. If it gives, sponges, or shows signs of dry rot, water is already getting into the subfloor. In houses near Spring Valley and Lakeside, this is one of the most common hidden problems we find during exterior door installation.
Our Process, Step by Step
We follow the same five-step process on every door installation in San Diego, whether it’s a $500 storm door or a $6,000 French door project. It’s the Kingswell Way: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails.
- 1
Call and talk to a person. When you call (619) 793-3829, a live human answers, not a voicemail tree. We ask about the door, the symptoms, the house, and when you’re available. Then we schedule a visit with a real arrival window, the same day or the next available slot.
- 2
Measure and quote on site. We come to your home, measure the rough opening, check the framing, inspect the threshold, and ask about anything you’ve noticed. Before we leave, you’ll have a written price. No ranges, no “we’ll send something over,” no revised invoice at the door.
- 3
Order with the right brand. We place the door order after deposit, using measurements taken on site. We tell you the brand, the model, the glass package, and the delivery timeline. When the door arrives, we call you to confirm the install date.
- 4
Install, seal, and clean. The install crew arrives in uniform, with a clean truck and all the tools needed. We remove the old door, prep the opening, install the new unit square and plumb, insulate the gaps, and seal everything. We haul away the old door and debris, then sweep and vacuum the work area.
- 5
Walk-through and written guarantee. We walk you through the finished door, demonstrate the hardware, and hand you the written Kingswell Guarantee. If anything fails within the guarantee period, call us and we return to correct it at no charge. Simple as that.
How Much Does Door Installation Cost in San Diego?
Door installation pricing in San Diego varies by door type, material, glass, and labor, but here are honest ranges based on the work we do every week. A standard front door replacement runs $1,400 to $4,500 installed. A basic interior door replacement is $400 to $900. A sliding glass door replacement runs $1,800 to $4,200 for a two-panel vinyl unit, and a French door installation runs $2,500 to $6,000. Storm doors land between $500 and $1,200 installed. Door repairs start around $150 for a service call and rise with parts and scope.
What moves the price: the door material (steel is cheaper, fiberglass is mid-range, solid wood is the highest), the glass package (plain versus low-e versus impact-rated), the frame condition (a rotted jamb adds labor), and the hardware grade. Coastal homes in Del Mar or Solana Beach usually cost more because salt spray demands corrosion-resistant hardware and better weathersealing. Inland homes in Santee or El Cajon sometimes need extra sun protection on west-facing doors.
How to avoid overpaying: get a written price before the work starts. Not a text message estimate, a line-item price on paper. Ask what the price includes (haul-away, flashing, trim, hardware) and what it doesn’t. Ask who shows up and whether the installers are employees or day-labor subs. A free estimate from us includes all of this, on site, with no obligation. You’ll know exactly what you’re paying before we order anything.

Frequently Asked Questions About Door Installation in San Diego
Door installation is the process of measuring, fitting, hanging, and sealing a new door in an existing or newly created opening. It includes framing the rough opening, installing the door slab and frame, adding hardware, insulating, and weatherproofing. In San Diego, door installation also means choosing materials that handle coastal moisture, UV exposure, and occasional high winds.
A standard front or exterior door replacement takes about four to six hours on site once the door has been delivered. Sliding glass door replacements usually take a full day, and French door installations can stretch to a day and a half if header work is required. Most doors arrive within two to four weeks after ordering, depending on the brand and glass package.
A standard door installation in San Diego generally runs $1,400 to $4,500 for exterior doors and $400 to $900 for interior doors, installed. Sliding glass and French doors run higher: $1,800 to $6,000 depending on glass, frame, and structural work. The best way to get an exact number is to call (619) 793-3829 and schedule a free on-site estimate; you’ll get a written price the same day we measure.
Yes, Therma-Tru is one of our primary entry door brands. We install Therma-Tru fiberglass doors because their foam-filled cores and composite frames stand up to San Diego’s coastal moisture better than solid wood. We can spec, order, and install any Therma-Tru model and finish you choose.
We answer calls 24 hours a day, seven days a week, and we can often schedule emergency door repair the same day for urgent issues like a broken lock or a door that won’t close. For non-urgent repairs, we typically schedule within a day or two. Call (619) 793-3829 and a real person will tell you when we can get there.
Every door installation comes with the written Kingswell Guarantee, which covers workmanship for the guarantee period. If the work fails within that time, we return and correct it at no charge. We also honor the manufacturer’s warranty on the door itself. You get the guarantee in writing at job completion, not buried in fine print you find later.
Clear the area around the door, inside and out, about four feet in each direction. Move furniture, rugs, and anything breakable away from the workspace. Secure pets in another room. If you have a security system sensor on the door, let us know ahead of time so we can coordinate removing and reattaching it. We bring our own drop cloths and cleanup supplies.
