LONE PEAK WINDOWS
Window replacement in Lehi, Utah
Lehi is two different window problems inside one city: century-old homes downtown, and twenty-year-old builder vinyl everywhere else.
Two Lehis, two completely different jobs
Lehi is where we are based, and it is the hardest of the six cities to generalize about, because it holds two unrelated housing stocks.
Downtown, on the old grid around Main Street, there are homes from the late 1800s through the 1940s. Original wood double-hungs, where they survive, are often worth restoring. What usually needs to go is the aluminum retrofit somebody dropped into the opening thirty years ago. Old openings are rarely square, and measuring them properly takes longer than measuring a subdivision. Anyone who quotes an 1890s house off a phone call has not measured it.
Then there is the other Lehi: Traverse Mountain, the Thanksgiving Point side, and the subdivisions that went up between roughly 2000 and 2015. Those homes got builder-grade vinyl, which was reasonable when it was installed and is now twenty to twenty-five years old. That is squarely inside the range where insulated glass seals start failing, and it tends to happen across a whole street inside a couple of years, because the whole street was glazed in the same month from the same lot of units.
We work every part of Lehi: historic downtown, Traverse Mountain, the Thanksgiving Point area, the neighborhoods along the Jordan River on the north end, and the newer building out west.
Point of the Mountain wind, and unshaded afternoon sun
Point of the Mountain is known for wind for a reason. Paragliders fly it because the air moves there reliably, and homes on Traverse Mountain and the north end of Lehi live in that same air.
Wind is a seal problem before it is a glass problem. A window that whistles is telling you the perimeter seal or the weatherstripping has lost the fight, and that is sometimes fixable without replacing anything. We will say so if that is what we find.
The bigger issue on the west and south sides of Lehi is unshaded afternoon sun. Newer subdivisions have young trees, which means the glass takes the full load from about two in the afternoon until sunset for the first fifteen or twenty years of a home's life. A low-E coating and the right solar heat gain number matter more here than the frame material does, and a salesperson who only wants to talk about frames is skipping the part that changes your July power bill.
Lehi is home. We are a Lehi-based business, so a walk-around here is usually the same week you ask for it.
Lehi questions we actually get
We are downtown, in a house from the 1910s. Can those windows even be replaced?
Yes, and often the better answer is that some of them should not be. Original wood double-hungs from that era were built to be repaired, and where they have survived they are frequently worth restoring. What usually needs to go is the aluminum retrofit that went into the opening thirty or forty years ago.
The real constraint downtown is the opening. Century-old rough openings are rarely square, they are rarely the same size as each other, and every one has to be measured on site. That is why we will not price an 1890s or 1910s house off a phone call. Licensed Utah window installers do the work, and the warranties are in writing before anything is ordered.
Four houses on our street fogged up within about a year of each other. Is that normal?
It is normal, and it is not a coincidence. If you are in one of the subdivisions that went up between roughly 2000 and 2015 anywhere from Traverse Mountain to the Thanksgiving Point side, your street was glazed in the same few months, from the same production run, by the same crew. Insulated glass units have a service life. When a whole block's units were made together, they tend to reach the end of it together.
The south and west elevations usually go first, because they take the most thermal cycling. Nothing is wrong with your house.
Does the Point of the Mountain wind mean we need a special kind of window?
Not usually a special window, no. Wind is a seal problem before it is a glass problem. A window that whistles in a storm is telling you the perimeter seal, the weatherstripping, or the sash has lost the fight, and that is sometimes fixable without replacing the unit at all. We will say so if that is what we find.
What the wind does change is how much the quality of the install matters relative to the sticker on the frame. The thing that actually shows up on a July power bill out on the unshaded west side of Lehi is the low-E coating and the solar heat gain number.
Real rebates. No tax-credit stories.
The federal window tax credit expired December 31, 2025. It is not available for windows installed in 2026. If a quote you are looking at includes a federal tax credit, the number at the bottom of that quote is wrong. What is actually on the table for Lehi homeowners in 2026:
Up to $50 per window from Rocky Mountain Power's Wattsmart Home program, plus $2.50 per square foot from Enbridge Gas ThermWise on gas-heated homes.
See the full conditions for both programs, including the U-Factor threshold and what has to be on the paperwork.
Figures reflect published utility program terms as of October 2026. Rebate approval is made by the utility.What every job includes
A licensed Utah window installer. The exact window and price in writing. Manufacturer warranties on paper. Written three-day cancellation rights on every in-home sale. One price that does not change.
