Job Stories From Oakdale, CT
Carpeting Transformation in Oakdale, CT

This Oakdale, CT basement was not visually appealing, especially it's carpet. Traditional carpets are made from organic materials, which can cause mold and mildew. This family wanted a change of scenery, so they gave us at Connecticut Basement Systems a call to come and help out!

Our team came out, and removed the old carpet, before installing our MillCreek Wood Laminate Flooring in the area. The synthetic wood material it is made from is 100% waterproof, and will not buckle or rot if it gets wet. It is also a healthy option,  as it contains no formaldehyde, doesn't support bacterial growth. This family now has a safer basement, and one they feel proud to invite friends in!

Basement gets water sometimes
Project Location: Oakdale, CT
I have groundwater seeping up through my concrete foundation into the basement (on a slope, so one half is mostly below grade; the other half is a few feet below grade). I only saw this 2-3x a few years ago, but this year it is very bad and I'm ready to install a drainage system. The water mostly comes into the unfinished half, but today I saw a puddle in the semi-finished half. It pooled overnight last night and it has not rained in days. My property is quite low (close to water table). You did an interior French drain for a co-worker and they recommended you.
Project Location: Oakdale, CT
I have 5 original metal frame basement windows (31.5" x 13.5" approx) that I need to replace and I am having a horrible time finding someone to do this at all. And if they can, getting it done at a reasonable cost. One is broken so I'd like to get it done before winter, and if I have to I'll try and do it my self from videos I've watched on line but would like to avoid that hassle if I can them replaced correctly and reasonably priced.
