Door and Window Installation in Apex, NC
Licensed and insured, about 25 minutes from our base, with a fixed written price before any work starts.
The sill or trim below a window feels soft or shows a stain, or a patio door drags, jumps the track, or will not stay latched shut. Those are the calls we take most often from Apex homeowners, and neither one improves on its own.
RK Renovation handles door and window installation across Apex and the rest of Wake County. Entry doors, patio sliders, interior doors and replacement windows set plumb, flashed properly and sealed against Carolina storm driven rain.
What the price covers
- Opening inspection and correction. Plumb, level and square checked at every corner, with rot, shims or minor framing correction addressed before a new unit ever goes into the hole.
- Removal and disposal. Old doors, sashes and frames removed carefully to avoid damaging siding or interior trim you are keeping, hauled off the same day.
- Flashing and sill pan installation. A sill pan or flashing tape system that sheds water out and away from the framing, installed before the new unit goes in rather than relying on caulk alone.
Door and Window Installation in Apex, in practice
Most window and door problems trace back to the opening rather than the unit itself. A house in Apex built more than thirty years ago has usually settled a little, which means the rough opening is no longer plumb, level or square even if it started that way. Setting a new unit into that opening without correcting it forces the frame to twist, and a twisted frame binds a door or leaves a window that will not latch fully. We shim to true plumb and square at every corner rather than to the existing framing, and install a sill pan under the unit so any water past the exterior seal drains back out instead of sitting on bare wood at a Wake County crawl space or slab edge.
The insulation packed around a new door or window jamb matters as much as the unit itself, and it is easy to get wrong. Standard high expansion spray foam can generate enough pressure to bow a jamb inward, which is why a brand new window can start binding within a week of installation. We use low expansion foam rated for doors and windows, or backer rod and sealant on tighter gaps, so the frame stays true. On the glass side, U factor and solar heat gain coefficient matter more in Apex than most realize, given our climate zone carries a real winter heating season and a long, humid cooling season. A lower SHGC on west facing glass in Wake County cuts summer heat gain without losing the winter benefit.

What Apex homes need
Two housing worlds in one town. The Salem Street blocks hold turn of the century homes with real character and real quirks, while everything east of Highway 55 is a 1998 to 2015 subdivision with tall ceilings and hollow core doors.
Permits for structural, plumbing and electrical changes go through the Town of Apex Building Inspections. We file them, schedule the inspections and meet the inspector, so the work is on the record when you eventually sell.
We work across Historic Downtown Apex, Scotts Mill, Haddon Hall, Bella Casa and the rest of Apex, and we are about 25 minutes from our base.
Everything we do in Apex
How a Apex project runs
Four stages, each finished before the next begins. Typical duration is 1 day to 2 weeks.
Measure and inspect the opening
We check plumb, level, square and the condition of the framing and sill before ordering anything, since a bad measurement means a bad fit no matter how good the unit is.
Order and confirm lead time
Doors and windows are built to spec, so we confirm sizes and options before ordering and set a realistic install date around the actual lead time rather than a hopeful one.
Remove, flash and set
Old unit comes out, the opening gets corrected and flashed, and the new door or window is set plumb and square with the correct fastening and insulation.
Trim, seal and adjust
Trim goes back on, gaps get sealed, and every door and slider gets adjusted and tested through a full open and close cycle before we call it done.
Questions from Apex homeowners
Do older homes in Apex need full frame window replacement?
Often, but not always. We inspect the existing frame and sill before recommending it. Sound framing in a Apex house can sometimes take an insert window, which costs less and disturbs the surrounding trim and siding far less.
What door and window sizes fit Apex openings best?
Openings in Wake County vary a lot by build era, from narrow 1970s ranch openings to wide production builder units from the 2000s. We measure the actual opening rather than assuming a stock size and order to match it.
Do you handle patio slider repairs in Apex, not just full replacements?
Yes. A dragging or hard to lock slider in a Apex home is usually a roller or track problem. We assess it as a repair first and only recommend replacement when the frame or seal has actually failed.
What insulation do you use around the jambs?
Low expansion foam or backer rod and sealant, matched to the gap size and the manufacturer specification. Standard high expansion foam can bow a jamb inward and cause a door or window to bind right after installation.
