Get the number before the sales visit
Most window companies will not give you a price until someone is sitting at your kitchen table. That is a sales tactic, not a technical necessity. Here is what Denver homeowners actually pay, and a way to work out your own range in about fifteen seconds.
Then, if the number is in the range you expected, send one request and let up to four licensed local contractors compete for the work. The spread between the highest and lowest bid on identical Denver window jobs is routinely 40 percent. That spread is the whole reason to get more than one quote, and it is worth far more than any discount a salesperson offers to close on the first visit.
What Denver windows cost, by material

| Vinyl | $575 to $950 | 15 to 25 years |
| Fiberglass | $850 to $1,450 | 25 to 40 years |
| Wood or clad-wood | $1,000 to $1,900 | 30 years plus, with maintenance |

Why Denver is not an average window market
Three local conditions shorten window life on the Front Range, and every one of them changes what you should buy.
- Altitude. Denver sits at 5,280 feet. A sealed glass unit assembled near sea level arrives here with more pressure inside than out, and the panes bow permanently. That stress fatigues the edge seal for the life of the window. Units built for this market use a capillary breather tube or an altitude-adjusted gas fill. Ask which one, on every quote. It is the fastest way to find out whether a company actually works here.
- Hail. The Front Range is one of the most hail-exposed corridors in the United States. Hail rarely shatters modern glass, but it dents cladding, cracks vinyl at the welds, and destroys screens, and the water arrives months later. If a storm hit your house, this is an insurance question before it is a shopping question.
- Daily temperature swings. Thirty to forty degrees between afternoon and dawn is an ordinary Denver spring day. Every swing works the frame against the glass, which is the real argument for fiberglass on large or west-facing openings: it expands at nearly the same rate as glass.
How we get paid, in one sentence. Contractors pay us for the introduction. You pay nothing, ever, and the fee does not get added to your quote, because the contractors bidding on your job are competing against each other on price. The longer version is on our about page, and it is worth reading.

Service areas
Where our contractors work
Five cities, and the window problems are genuinely different in each one. Aurora's aluminium sliders are not Arvada's 1905 wood sashes.
Denver
Three markets in one city: pre-war wood sashes, mid-century steel, and post-1995 vinyl now failing on schedule. Landmark districts and basement egress covered.
Aurora
Aluminium sliders with no thermal break, and flight-path noise from Buckley and DIA. Both have specific fixes.
Lakewood
Mid-century ranch homes, steel casements worth restoring, and foothills wind that changes the specification.
Arvada
Olde Town restoration work at one end of the city, HOA architectural review at the other.
Westminster
The most predictable market in the metro. 1990s vinyl units reaching seal failure age together.
Not on the list?
Send your ZIP code anyway. We cover neighbouring cities where a contractor in our network already works, and we will tell you straight if we cannot help.
Common questions
Is this service really free?
Yes, to you. There is no fee, no membership and no charge of any kind for a homeowner. We are paid by the contractors who receive your request. That does not change the price you are quoted, because contractors bid against each other for your job.
How many contractors will contact me?
Up to four. We say up to four because it depends on how many licensed contractors cover your ZIP code and take your service type. If you want fewer, say so in the message box and we will limit it.
How soon will someone call?
Usually within one business day, and often within an hour during working hours. Speed of first contact is the single strongest predictor of whether a home services job goes well, so good contractors move fast.
Are the contractors licensed and insured?
We only pass requests to contractors who confirm they hold the licences their jurisdiction requires and carry general liability insurance. We are not the licensing authority, though, and we do not warrant anyone's work. Always ask for the licence number and a current certificate of insurance, and verify both yourself before you sign a contract.
What does window replacement cost in Denver?
Roughly $575 to $950 per window installed for vinyl, $850 to $1,450 for fiberglass, and $1,000 to $1,900 for wood or clad-wood. A ten-window house typically lands between about $5,000 and $19,000. Our replacement page breaks the numbers down properly.
Will you sell my phone number to anyone else?
We pass your request to the matched contractors and nobody else. We do not sell contact data to list brokers or marketing companies. The privacy policy sets out exactly what we collect, who receives it, and how to have it deleted.
