Lux Renovations was highly professional and did a phenomenal job with our basement. We are thrilled with the finished project.

We went from a mess to a completed project in 3 weeks! I found Lux Renovations after a bad experience with a contractor. The Lux team has restored not only my (now) beautiful basement but my faith in humanity! The entire team (John, Pete, Juan and especially MARIO!) were simply amazing. We went from a mess to a completed project in 3 weeks! Highly recommend!

Questions Portsmouth, NH Homeowners Ask About Basement Finishing From Lux Renovations

It’s common for folks to hear a number and think it’s ‘high.’ That is until they sit down with professionals who do this work day in and day out and go through the nitty-gritty details. We do this in order to make honest line-by-line comparisons and help you navigate the possibilities.

When you consider the costs/headaches of completely top-to-bottom custom drywall work, the price for a high-quality Owens Corning system makes a lot of sense! Your design consultant and project manager will ensure you fully understand the value you’re getting for your investment.

You bet! A large percentage of our basement finishing projects every year are financed. Just let us know you’re interested and we can walk you through our versatile homeowner-friendly options. For more information, please visit our Financing page.

Nope. We’ve focused on Owens Corning basement finishing since Day One. It’s all we do, so we’ve got over 10,000 installed basements under our belts.

Yes. We’re quite proud of our history in the region. We’re from here. We grew up here. We’ve raised families here. And we’ve built our careers here. There’s no other place like it!

We’ve grown over 20+ years in business. Today, we cover the entire East Coast region and beyond into Pennsylvania and New Jersey.

Once we get everything in order, schedule you, and begin transforming your basement, the average project takes us 3-5 weeks.

Our system involves proper and prudent planning. A lot goes into ensuring there aren’t any surprises for anyone involved. We aim to address all concerns and adjustments before we finish.
