Basement Remodel Client Testimonials

 

My experience with Lamont Bros. was fantastic.

They designed a brand new remodel of our basement, making sure that the architecture and design were exactly right.

The design and remodel process was clear and well managed. When we needed to make changes to the project, they were handled expertly and promptly.

We always had a clear line of communication with our project manager and designer.

I would absolutely recommend them to anyone looking to remodel their home.

Just do it. I promise you will not regret it.

Lamont’s process from consultation to final photos was an absolute breeze, and that only happened because of their clear communication and concise system.

They were honest about what we could accomplish with our crawlspace conversion and budget, and were able to get the most out of the entire experience (and then some).

Communication was at the forefront of our partnership, and I never had to second guess or wonder what was next in the timeline.

I proudly look at our basement knowing that Lamont’s team did everything I asked and more.

Amazing work by an amazing company.

Lamont initially converted our very dysfunctional basement into a welcoming place for our family.

We were so impressed with their work that we elected to have them update our kitchen the following year. Our family could not have been more pleased with the work!

The difference with Lamont is the attention that is paid to the client. I have used other construction companies in the past that would have our project as one of many and were often squeezing one or two hours in on our "side job."

Lamont is the exact opposite as you will have a dedicated team only working your job until it complete. This keeps things moving efficiently and streamlines communication.

We will use Lamont in the future for all upcoming projects. Finding a great, trustworthily construction company is a key to home ownership. Lamont Bros. is that company.

Our Basement Remodel Process

 

 

Why Remodel Your Basement?

  • Smart storage solutions maximize every inch of your basement’s potential.

Funding Your Basement Remodel

  • We structure financing for basement projects typically ranging $100,000-$250,000 using home equity loans that preserve your existing mortgage rate, or renovation loans that recognize the significant value-add of converting unfinished space into livable square footage.
  • Our basement-specific financing expertise helps lenders understand the unique ROI potential of basement conversions, which can add 600-1,200 square feet of finished living space at a fraction of the cost per square foot of building additions.
  • We coordinate with ADU and rental income financing when basements include separate entrances and utilities, helping you access loans that factor in potential rental income of $1,250-$2,000 monthly for basement apartments or in-law suites.

Return on Investment for Basement Remodels

  • Basement remodels offer exceptional cost-per-square-foot returns typically adding 70-90% of project cost back immediately, with our Portland case study showing a $210,000 basement remodel adding $166,000 in value while creating 800+ square feet of finished space.
  • Fastest payback period of major remodels with break-even often occurring within 12-18 months due to the dramatic transformation from unfinished to finished square footage, plus potential rental income of $15,000-$24,000 annually if designed as separate unit.
  • Dual-purpose investment potential creating both family living space and future rental income opportunities, while basement remodels typically cost 40-60% less per square foot than additions while delivering comparable lifestyle improvements.

From Dirt and Broken Concrete to a Media Room and Home Office

 

 

Going to the basement creeped me out and I had always wanted to make it a more functional space.

What Lamont Bros. did with our basement was incredibly smooth and we're really grateful.
