Window Replacement & Installation Contractor in Knoxville, TN

If the frame is solid and the problem is a draft, stuck sash, or failed caulking, repair is usually enough. If you see condensation between the panes or rotted framing, replacement is the better long-term option.

An insert, or pocket, replacement sets a new unit into the existing frame, which stays in place. It is less invasive and usually keeps the trim intact, but it depends on that frame being square, sound and dry, and it gives up a little glass area. A full-frame replacement takes everything out down to the rough opening. It costs more and disturbs more trim, but it is the only way to see and correct what is behind the frame, and the only option when there is rot or the original flashing was never done.

Yes. New-construction windows carry an integral nailing fin that fastens to the sheathing and laps into the weather barrier. We install them on additions, new builds, and on remodels where the siding is coming off anyway. We also install replacement windows into existing openings.

Sometimes, and it depends on the method and the condition of the opening. An insert replacement often does not require it. A full-frame or nail-fin installation frequently does, because the flashing has to lap into the weather barrier behind the siding. If siding needs to be removed and reset, we put that in the written scope rather than discovering it on the day.

Most leaks trace back to missing or improper flashing at the window-to-wall connection, not the window unit itself. We inspect the flashing and house wrap integration before recommending a fix.

Sealant is part of the assembly, not the whole of it. It has a service life, and when it ages the wall still has to shed water. The building code calls for corrosion-resistant flashing applied shingle-fashion at window openings so each layer drains onto the one below. A window held in with caulk alone is the most common cause of the drafts and stains we get called about.

Condensation between the panes means the thermal seal inside the insulated glass unit has failed, and that seal cannot be restored. The glass unit is replaced, which does not always mean replacing the whole window. We look at whether the frame and hardware are still sound first.

Usually the installation rather than the unit. Loose tolerances at the opening, missing insulation in the gap, or a window sealed with caulk instead of flashed and insulated will all produce a draft through a brand-new window. It is worth having the opening looked at rather than replacing the window again.

We stop. Concealed rot, damaged sheathing, framing damage, water damage and insect damage are not visible until the unit is out. We document what we found, explain it, price it, and issue a written Change Order. You approve it before any additional work happens. Hidden repair is not assumed in the original estimate.

We coordinate the permit requirements that apply to our contracted window scope.

We complete the interior trim, drywall and finish work that the approved contracted scope requires, so the opening is left finished rather than handed back as a hole with a new window in it.

Two separate things. Full window installation and replacement carries a Five (5) Year Limited Workmanship Warranty, and window repair or partial-repair scopes carry a One (1) Year Limited Workmanship Warranty, both subject to the signed agreement and the scope it defines. The manufacturer product warranty is separate, comes from whoever made the window, and varies by brand and model.

We install a range of common window brands and styles based on the home, the opening, the project scope and the product selected. Windows may be sourced through suppliers such as ABC Supply, Lowe's and Home Depot. Product warranties vary by manufacturer and model, while our workmanship warranty applies separately to our installation work.

New windows reduce heat transfer through the glass and air leakage around the frame, and most homeowners notice the comfort difference first. What the bill does afterwards depends on insulation, air sealing and the HVAC system as much as the windows, so we do not publish a percentage. The U-factor and SHGC on the NFRC label are the figures that describe the window itself.

Most single or multi-window replacements are completed in one day. Whole-house replacements typically take two to four days depending on the number of openings.

Yes. We handle single window replacements as well as whole-house projects — there is no minimum requirement.

If both are planned, yes, and the windows are usually better done during the siding work. With the siding off, the weather barrier and the opening are visible, the flashing can be lapped into the barrier correctly, and nail-fin windows become an option. Doing the windows afterwards means cutting into finished siding.

Our standard deposit is 33%, with the balance governed by the signed agreement.
