Foundation, Drainage & Egress Windows · St. Charles County and West St. Louis County

Fix the water before you finish the basement

Cracked walls, water at the cove joint, a sump that runs every rain. We diagnose where the water comes from and fix it, with drainage, grading, wall repair and sump systems, and we cut and install the egress windows a legal basement bedroom needs.

What's included

  • Foundation crack and wall repair
  • Interior drain tile and sump pump systems
  • Exterior drainage and grading
  • Egress window cutting, wells and ladders
  • Window well drains
  • Structural repair and beam replacement

Foundation: our work

What moves the price

  • Crack repair versus wall stabilization
  • Interior drain tile and sump versus exterior drainage
  • Egress window size and whether it is cut into block or poured concrete
  • Window well type and drain
  • Access to the work area

We quote in writing after a free walkthrough. No published prices: every job is different and a number without a walkthrough is a guess.

Materials and options

  • Epoxy and polyurethane crack injection
  • Interior drain tile and sump pump systems
  • Egress windows, wells, ladders and covers
  • Carbon-fiber and steel wall reinforcement

Permits and inspections

An egress window is a structural cut that needs a permit and inspection; drainage work inside the foundation generally needs a plumbing inspection for the sump. We handle both.

St. Charles County's incorporated cities each run their own building division; unincorporated areas go through the county. We know all of them.

Questions people ask

Straight answers, the same ones we give on the walkthrough.

How much does an egress window cost?

It depends on the wall material, the window size and the well. We quote after seeing the wall.

Is an egress window a permit job?

Yes, it is a structural cut. We handle the permit.

Do you finish the basement afterward?

Yes. Most of our basement finishing jobs start here.

What causes water at the bottom of the basement wall?

Usually hydrostatic pressure at the cove joint where the wall meets the floor. Interior drain tile and a sump relieve it.

Is a foundation crack serious?

Hairline shrinkage cracks are common and sealable. Horizontal cracks or bowing walls are structural and need reinforcement. We tell you which you have.

How long does the work take?

Two to five days on site for most drainage and egress jobs.

Do you guarantee the basement stays dry?

We stand behind our work and tell you what each system does and does not cover. Grading and gutters outside still matter, and we point out what to fix there.

From our Google Business Profile and Facebook page, shown as written.

Sean and John came in and turned my abysmal bathroom into something amazing. Great service, professional, timely and excellent at communicating. They will be back to do many other projects for me.

Sean, from SC2 contracting just finished building my new deck. I couldn't be more pleased! Not only did Sean do a great job, but he made the project very pleasant by always communicating when he'd be at my house, if it was okay to work on weekends, and what was happening next. He clearly is a man of high integrity, taking pride in doing a good job and working hard every day to get the job done(even in the St Louis heat we had this summer).

I will definitely be in touch with him again to do other projects for me, and have no doubt I'll get the same wonderful results!!
