"Everything went well.? Bob and his crew are true professionals.? I had a few ideas about how I wanted the basement to look but wasn't sure? how it could be done in a relatively small space.? I live in a condo/townhouse and only wanted half the basement finished.? Bob was very helpful with his design ideas and I was totally impressed with the results.? He exceeded my expectations by finishing the task on time and maybe a few days early.? He is very upfront with costs, expectations, and time management.? He frequently updated me with his teams productivity and wanted my input regarding such.? The results are fabulous!? My friends have complimented the fact that I still have plenty of "storage space" in the unfinished part of my basement and a beautiful room in the other.? This room consists of a reading nook with under-the-bench storage and above shelving; a small office area; and a room for watching t.v. and entertaining.? I chose to do the painting myself...Not an easy task but Bob was there to answer my questions about that as well.? Once the carpeting is in I will have beautiful pictures to share with family and friends.? I couldn't be happier and will definitely call this company for my bathroom and kitchen in the future."

"I would highly recommend MMP Construction. Matt and his team are knowledgeable, friendly, and extremely hardworking. Even after running into some unexpected structural issues once the walls were opened up they still managed to get the job done in the time frame quoted by working extra hours and weekends. I was truly blown away by the level of dedication and service. Anytime a challenge came up, someone on the team was quick to provide a great solution. And the finished product is absolutely gorgeous. I would hire them again in a heartbeat.

"We hired Tom for a kitchen & half-bath remodel in 2019. As with all remodeling projects, especially a kitchen remodel that disrupts your life, Tom was wonderful at communicating and kept the project on time and on budget. Tom stands behind his work and quickly remediated any issues (which are always inevitable with these projects) and we can absolutely say that we are still 100% satisfied a year later. We completely trusted Tom to make our kitchen remodel dream come true and would hire him again should another project come up!"

"I would not hesitate for a second hiring Horsman Builders for any of my house projects or remodel, in fact that is what I will do from now on. I was nervous starting a project having to handle things on my own but Tim made me comfortable with a detailed estimate, answered all my questions, kept me informed about the work, the site was always clean and the result is awesome, my neighbor was commenting on how great it is just checking it out from a window. Fair price, excellent quality and great customer service. A+"

FAQs for basement remodeling projects in Manchester, NH

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.
