Walkthrough and Warranty
We complete the punch list together and stand behind the work with a written workmanship warranty.
Every project gets a dedicated manager, a written schedule, and weekly updates.
Why homeowners choose Keystone
Big projects go sideways when no one is accountable. We built our entire process to remove that risk.
Fixed, written estimates
A detailed scope and price before a single nail is driven. No surprise change orders, ever.
One project manager, start to finish
Your dedicated PM runs the build and sends a written update every week without you having to ask.
In-house craftsmen, not a sub chain
Our own carpenters and finishers do the work. Quality does not get diluted across four layers of subs.
Two-year workmanship warranty
We stand behind our work in writing. If something is not right, we come back and fix it.

Keystone built our home exactly the way they said they would, on the timeline they promised. The weekly updates made a huge project feel manageable.
SASarah and Mark T.
New custom home · Shadyside
Our kitchen remodel came in on budget and the crew treated our house with respect. We get compliments every time someone walks in.
DRDiane R.
Kitchen remodel · Squirrel Hill
As a property owner, schedule is everything. They delivered our office build-out two weeks early and the quality has held up beautifully.
JKJames K.
Commercial build-out · Strip District
The addition matches our 1940s home so well that visitors cannot tell where the old house ends. That takes real craftsmanship.
