"I hired Silmac construction to remodel my basement. They put in a three-quarter bath, kitchenette, and finished the rest of the basement. This included cutting foundation for full size windows, putting in a new zone for heating and cooling system, and all the plumbing and electrical work needed. They were very professional and did an excellent job. I have gotten many compliments on our basement and I will hire them again to do work on my house."

"Pedro Quissanga was wonderful throughout the process. The project started out as a porch window replacement with an architect drawing plans, but once we started construction, we discovered that the whole underneath part was rotting and needed reconstruction. Pedro and his crew were hard working, reliable and careful, and his price for all of the work was very reasonable. When something went awry late in the construction, Pedro took it seriously and got people over within hours to locate the issue and fix the problem. Even though the project ended up being much more difficult than initially expected, there were never any unexpected charges and the additional work was at a consistent high level. We recommend Crystal Renovations without reservation and have several neighbors using them now for small-to-medium sized projects."

"When we started our plan of remodeling, the first thing we did was the complete roof replacement including kitchen vent & duct pipe installation to the roof, and new installation of attic ventilation. MMP did not only completed it just as agreed but also very efficiently. The crews were friendly, professional, and careful. The jobs were carefully managed and implemented effectively. I was impressed by Matt, who is the manager, and he does an outstanding job in managing the crews and the progress of the situation, and the communication was clear and always to the point. We then moved to initiate a search for a contractor of two bathrooms remodeling after completing the roof and attic vent, MMP was one of the many candidates. Matt has had not only the best idea and proposals but also shown an impressive & professional sense of evaluating the project accurately, including the possible structural modification as well as a competitive estimate of the cost of the build. His proposal included a rebuild of a wall of the bathroom to expand another one adjacent to it. Matt accepted to use my schematic design image (made with a software tool) and a spreadsheet list of the fixtures that I created - as many as fifty items including TOTO, Grohe, American Standard, Panasonic, and IKEA - to start the job (later changed some of them due to local plumbing code compliance) After beginning the bathroom remodel project, Matt shared what jobs will be done with us timely and efficiently via text so that we feel comfortable enough in knowing what is going on while living in the house of dust & noise from remodeling. The crews, Zen and Mark, were very courteous, extensively experienced, reliable, and friendly with excellent communication, sometimes with songs of 80s rock music. They ask me when more precise specifications are needed and notified me when they feel advance notifications are required. When a change is necessary due to inspection, they informed me and clarified what and why. I have never felt uncomfortable in living together with the remodel job which has lasted over four months. The completed two bathrooms were stunning, just as I imagined. Matt, Zen, and Mark have proved their strong & thoughtful expertise and lived up with my request patiently until completion. Great job. A home remodeling project cannot be successful without having a trusted partner, and my experience with MMP has led me to be glad to share my confidence that MMP has a credential to become your reliable partner to manage a construction project together."

"Mostly well.  We purchased the Big Deal for 2 painters for a day which said it would be 2 painters for 9 hours for a total of 18 hours.  They showed up with 3 painters and said their day would end earlier since they would hit their 18 hours sooner with 3 people.  I do wish we had known that in advance, but it worked out.  They told at the beginning that the oil based primer wouldn't have time to dry because it needs to dry for 24 hours, so we had to go back to get latex primer while they prepped.  That was disappointing because everything I read was that the soot should really be covered with oil based primer so that it didn't bleed through.  I wish they had told me that when we were exchanging emails about the job, but maybe I should have known that already.  We had to have the job done that day though, so rescheduling wasn't really an option.  When my husband returned to the store to get latex paint, they asked him to pick up a pack of rollers also.
They did a quality job, painting the ceiling which was probably difficult since the family room had two levels, with part of the room having very high ceilings with skylights, and another part of the ceiling was over a staircase to the basement.  Since we had purchased a deal that was for a specific time frame, they covered a lot with their time, and my husband was set to complete what they didn't get to.  We were happy they were able to prime and paint the entire family room for the most part, and able to prime the bathroom as well.  
They were flexible and worked with us with what to do.  We needed to paint the family room and bathroom and kitchen.  We only wanted to pay for the one day and my husband was prepared to finish whatever was left over himself.  We were hoping they would finish the family room at least.  At some point my husband saw how much time was left, and decided he would rather have them prime the bathroom instead of cutting in along the floor in the family room with the paint (since my husband would rather finish the paint than deal with priming the bathroom himself).  They didn't have a problem with that.
The rooms turned out very well.  Would use them again in the future.

"The most important part of a remodeling project is your contractor. It is the contractor that determines how smoothly the project goes and how pleased you will be when it is finished. Liam Neary is the contractor I would want to work with again. We actually enjoyed the remodeling process because of Liam. Liam was very attentive to all our concerns throughout the project. All work performed by Liam himself was exceptional. He is neat, prompt, and organized with a-plus communication. Liam is honest, congenial and eager to please. Subcontractor work occasionally did not rise up to Liam's standards. Whenever we pointed these minor details out, Liam always rectified the issues. We love our new kitchen!"

Basement Remodel FAQs, answered by experts

Key trends include home gyms, theatre rooms, additional rooms (bedroom/office), and more, with personalized styles reflecting individual preferences.

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.

If you’re not sure which method of raising the ceiling is best for you, here are a couple of considerations to help you make that decision. A professional ceiling company will be able to help you determine the best option for your home.

  • How long you are planning to live there: although raising the basement ceiling will increase the value of your home, if you’re planning to sell the house, then go for raising the house.

  • The condition of the foundation: to lower the floors, your foundation has to be intact whereas raising the house will allow you to restore the damaged foundation.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.
