The lines we install

  • ProVia
  • Soft-Lite
  • Pella
  • Sierra Pacific

Every reason people call us about doors

Built to fit your house, not a catalog.

Tap any one — here’s what actually changes when the door’s done right.

  • Lower energy bills

    A foam-core door seals where an old one leaks. ProVia’s Signet entry door runs a U-factor as low as 0.16; the Endure patio slider hits U-0.17 on Neopor graphite foam; and the Soft-Lite Kingsroyal patio door is built on the same R-5 ComfortFoam family as our primary windows.

  • Curb appeal you choose

    Signet is the most customizable door we carry — the most realistic woodgrain, in cherry, mahogany, oak, fir, and knotty alder, with glass, sidelites, and transoms to match your house instead of a catalog page.

  • A patio door that glides

    An old slider drags because the rollers are shot and the track is bent. A new Soft-Lite Kingsroyal sets level on fresh rollers with a steel-reinforced frame — smooth slide, solid lock, every single day.

  • No more foggy patio glass

    Fog between the panes means the seal failed. Warm-edge glazing — ComforTech on ProVia, the metal-free Super Spacer on Soft-Lite — keeps the glass edge warmer, so seals last longer and winter condensation drops.

  • Fresh air, no bugs

    ProVia’s Spectrum storm door carries an InVent retractable screen top and bottom: slide the glass and the screen is already there; slide it away when you don’t want it. Open the house up on a nice day without the bugs.

  • Locked up tight — one key

    ProVia’s Legacy is 20-gauge steel, about 49% more steel than a typical door. And because our entry and storm doors are both ProVia, the storm door can be keyed to open with the same key as your front door.

  • A quieter entryway

    A solid, well-sealed door plus multi-pane patio glass shut out the street. Pella’s Lifestyle glass package cuts outside noise up to 52% versus single-pane.

  • Backed in writing

    Every ProVia door carries a transferable Lifetime Limited manufacturer product warranty, plus 5-year Excel labor and no service-fee gate when you call us out. It’s in the contract.

THE EXCEL PROMISE

How we do business.

Three things we hold to on every job — the reasons families call us back and send their neighbors.

  1. Same owner, same crews

    Chris still runs the company he started, and the same installers come back job after job. You're never handing your house to a stranger.

  2. Education over selling

    We walk you through the options and leave a written proposal — not a high-pressure pitch. You decide on your own time.

  3. The care we'd want at home

    Most of our work is repeat and referral — because every job gets the same care and craftsmanship we'd want in our own homes.


WHAT TO EXPECT

  1. 01 Call or form
  2. 02 Schedule visit
  3. 03 Design appointment
  4. 04 Final measure
  5. 05 Install (average 1–2 days)

Most projects run about 6–8 weeks from first call to install day.

IN THEIR WORDS

What our doors customers say.

“Love my new front door! Matt is a great salesman who knows his products front to back. He was super helpful and patient choosing the best design for us. My wife and happy with our choices. Installation was great and painless. Steve cleaned up after his installation and made sure my children stayed clear of the work area. Couldn't recommend this company anymore.”

“I used Google reviews in helping me decide which window companies to get an estimate from so I should probably give back. My experience was excellent from start to finish. I had to replace my sliding glass door. Since the door was around 40 years old, they no longer make them in that size. The salesman Tony was great and after the contract was signed, Excel did everything from start to finish. They contacted my HOA and got their permission to do the install. I never even talked to them. They took care of getting the permits from the city as well. The contractors that did the install were as good as they come. They built the wall in to accommodate the size of the new door and did exceptional work. They spent approximately 4 hours doing the install. They took the time to answer any questions I had and I am very happy with the final product.”

“I was in need of a new front entry door so I call a few places for estimates. Excel was the first company to come out and these folks that ended up installing my door. I picked Excel because they made me feel very comfortable about the process, explained the scope of work needed in great detail and they just seemed trustworthy. I'm happy with my decision, the quality of the door and the installation. I wouldn't hesitate to call them in the future.”

“Excel installed a majority of updated windows in 1990. Excel did our siding in 1992. Then in 1995 the family room windows and patio double door were installed. After 30 years, windows are in good shape, 28 years, and the siding is attractive and functional, and the patio door, with much abuse from 3 dogs, only needed attention after an oven energetic puppy broke the seal between the Thermopylae glass and needed replacement. A recent puppy addition thought the sliding screen patio door screening would be a great plaything. We called Excel and they scheduled, arrived, removed, took to shop for repair, and returned and reinstalled the next day. They did a great job and updated the spline with the new screening. They are a great company that believes in quality, value, and especially customer service. We'll be requesting a quote to re-skin our 8' X 12' out shed next month. If you want value, dependability, and professionalism, EXCEL should be checked out.”

“Amazing Company from start to finish! Friendly, honest and knowledgeable staff. We would HIGHLY recommend! We will have them back next year to get the second floor windows done. They installed two large windows on the main floor and a new patio door. The transformation to our main floor is phenomenal! The installation crew was extremely professional, neat and tidy. They were extremely friendly to our dogs and toddler (even when they were in the way). They were very careful around our floor beds. We were impressed with the clean up!! I can't not speak highly enough of this crew!!!!! THANK YOU GUYS!”

“I had a great experience with Excel in replacing my 2nd level sliding door and 3 double hung windows. I contacted several contractors for the project and in the end chose Dominic (owner Excel) to be very trustworthy in handling the complicated issue of water seepage from my balcony sliding door. He gave me a very reasonable estimate for both projects compared to other highly priced competitors and also installed upgraded products. Everything from start to finish was exceptional. Even the installers themselves....Juan and Salvadore.....very meticulous in their work and explaining everything to me during the install. I will definitely reach out to them again for other work and refer them to friends and family.”

Doors — common questions

Steel or fiberglass for my entry door?

Both are solid. Steel — ProVia's Legacy — is 20-gauge and budget-friendly, and it resists dents. Fiberglass — Signet and Ascent — takes a realistic woodgrain finish, won't rust, and won't need repainting. We'll walk you through the trade-offs at the measure.

Sliding or French for a patio door?

A slider saves space since nothing swings into the room — our go-to is the Soft-Lite Kingsroyal, with ProVia Endure as another vinyl option. A French door, like ProVia's steel Legacy French, swings open for a wider entry and a more classic look. We bring both to the consultation.

Can my storm door use the same key as my front door?

Yes. Because we install ProVia on both entry and storm doors, the storm door's lock can be keyed to match your front door — one key for both.

What brands do you carry?

Entry and storm doors are all ProVia. Patio doors are multi-vendor: Soft-Lite Kingsroyal (our go-to), ProVia Endure and Legacy French, Pella Lifestyle, and Sierra Pacific.

What warranty comes with the door?

Every ProVia door carries a transferable Lifetime Limited manufacturer product warranty; Pella patio doors carry Pella's limited lifetime terms with 20-year glass. On top of the manufacturer's product warranty, Excel warrants the labor for 5 years — and there's no service-fee gate when you call us out. The specifics are written into your contract.
