"Response to my query was immediate. Husband and wife team, Gisele and Amir, came out to the house and wrote down all the things I needed done around the house. The jobs were many and varied and ranged from replacing basement windows, to creating backing for my lower kitchen Lazy Susans (so things don't fall off in oblivion), to staining a deck railing, to repainting basement and outside concrete walls, to reglazing and caulking windows, to creating a trap door for the plumbing, to sealing off/covering some dangling electrical wires, to patching a hole in an inside wall, and more. I got a full 4-page written quote ahead of time and was satisfied with it so I had them begin work right away. I left the house for a few days to go on a business trip and when I came back ALL of it was done and everything was cleaned up. There was only 1 thing that needed a bit more work and Amir came back and did this as soon as we could get it arranged. I liked their work ethic and professionalism so much that I have hired Gisele and her cleaning company to do my monthly housecleaning. We've had one cleaning so far and it was done well. Gisele speaks both English and Portuguese and will do translating when necessary for Amir and her cleaning staff. I am having fun learning some Portuguese words, too! They are delightful, easy to correspond with, up-to-date with technology (you can text and Venmo them), and I will continue to use their services."

"Every step of the way was above expectations. Scheduling was easy, I was notified of ETA, and Al, our technician, was prompt and thorough. We needed our gas fireplace cleaned, and the job was done thoroughly, carefully, and efficiently. Our 25+ year old fireplace now functions perfectly and looks amazing. Can’t beat the price. 10/10 recommend."

"Working with Jodi and her amazing crew could not have been a smoother experience. From the first visit, to the quote, to the schedule and execution was straightforward, dependable, and cooperative. We asked Jodi to begin the quote with just the upper level (2nd floor and attic) of our home due to our budget restrictions. She was willing to work with us and was so flexible. We decided to give Jodi and her crew the entire job because of how reasonable and efficient her pricing was. No surprises. Such a hardworking team, they transformed our 150 year old wooden siding from looking beat up and weathered to looking absolutely fantastic. No mess left behind, fast and great quality workmanship. Highly recommend!!"

"My wife and I couldn't have been happier with the quality of work performed by Pavia Construction. The tiling work and designs were excellent. We chose a color scheme & asked they be creative. The live-edge wood vanity with stone vessel sink with bamboo-style faucet off-set is really stunning! Couldn't have asked for anything better!"

"I have now had 4 pickups from this company. Each time it has been with different items: I have had my kitchen remodeled,  a deck torn down and rebuilt, a new roof put on, old fencing disc arded, and a yard cleanup. The only difference in pricing was for the roofing and even though ti was more money it was STILL CHEAPER than a dumpster!!! I don't know how these guys do it, but they pickup on time, without issue andfor the cost quoted. I have turned each of my contractors onto them - now they are using them. SO MUCH cheaper and better service than any dumpster company I have used!"

Basement Remodel FAQs, answered by experts

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

It is common for a contractor to ask for a down payment before starting a project, especially for jobs that require purchasing materials and equipment or hiring a crew. The deposit amount can range from 10% to 50% of the total job cost. While a request for up to 50% is not unusual, a contractor should not ask for more than that, and you should never pay for a project in full before the work has begun. To protect yourself, always discuss payment terms before starting and have a written contract that outlines the project timeline and expectations. Additionally, be sure to hire reputable contractors and check their licensing and insurance before the project begins.
