Excavation and site work in Westminster
Westminster sits right next to Broomfield, so it is one of the easiest towns for us to get to for a site visit, an estimate or the work itself.
Typical Westminster projects for BK Builders are digs for home additions and new houses, trenches for water, sewer and electrical lines, regrading yards that hold water near the foundation, and concrete slabs once the ground is ready.

Drainage regrades in established neighborhoods
A lot of Westminster homes were built decades ago, and yards settle over time. When water starts running toward the house instead of away from it, the fix is usually a regrade: cutting and filling to restore positive slope away from the foundation and toward a safe outlet.
Two counties, one city
Westminster spans both Adams and Jefferson counties, but building permits for property inside city limits go through the City of Westminster. We call in Colorado 811 locates before every dig.

Westminster FAQ
Do you work in both the Adams and Jefferson County sides of Westminster?
Yes. We work anywhere in Westminster, on either side of the county line.
My yard drains toward the house. Can you fix it?
That is a common Westminster job. We regrade to move water away from the foundation and can tie in with other drainage work your property needs.
Can you trench for a new water or sewer line?
Yes. We dig the trench to the depth and route your plumber or utility needs, then backfill and compact it properly.
