"Angel was responsive to my inquiry by email. Came out for an estimate to install stock cabinets, counter top and sink as well as all the plumbing. The day he was scheduled to come to install he called me to explain he had made a mistake on his estimate and wanted to talk with me first because he said he would not just come to do the work then tell me, this was for $20.00! that impressed me a lot. He was so careful of my home protecting the area he worked in he did a quality job! He was efficient an organized."

"I was extremely impressed with Tony Maniscalco's professionalism, accuracy and dependability.  He has been extremely responsive to any and all questions, etc. I have.  He started the process with me and recommended an an architect that was awesome and quick.  We were ready to break ground within two weeks of close of escrow.  Since there have been a ton of guys working on various stages of the house.  Neither I nor any of my friends have ever seen a house go up this fast.  We started on March 1st and are scheduled to be completely down by the first week of July.  At this point I can't see anything that would preclude that from happening.Tony has accommodated all of my requests, integrated my design and construction wishes and been able to offer suggestions on the best way to put certain things together.  His team is professional and courteous as well.  I have been over there multiple times and have never met a crew member that I didn't like.  They have also been very respectful of my house even thought it's not finished it.  We are in the process of putting the final touches on.  It has been great working with Tony on this project and am looking forward to enjoying our awesome house once it is done.  I'll update once it's finished."

"We recently did some upgrades to our home and had lots of scraps left over, we also decided to do a bit of decluttering. Once we saw the mound of things we knew we needed a professional. Andres was referred to us by a good friend. He was very flexible with our schedule since we are pretty busy and was at our place the very next day! Him and his crew cleaned everything up quickly and hauled it all away. They were very friendly, professional and very efficient. I would definitely use them again and refer to everyone I know."

FAQs for basement remodeling projects in Los Alamos, CA

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
