New basement stairs and railings brought a May 2026 customer to MW Carpentry and Construction. The customer praised Marc's communication, said everything happened on time as promised, and described the price favorably. The West Boylston business lists frame-to-finish carpentry and handyman work; customers describe projects ranging from individual doors to deck and porch improvements. Railings feature in several dated accounts. In an October 2025 Google review, a customer said Mark installed railings on new front stairs, then replaced another set after they liked the first result. An April 2025 reviewer described Marc replacing wood deck railings with vinyl and adding a stair gate. That customer said he started as planned and accommodated changes. They also credited him with referring them for power washing and staining, which was completed before he returned to finish his own work. A January 2022 customer described replacement decking, railings and privacy lattice for a screened porch and deck. They said Marc asked for their input on design choices as the project progressed and provided the only itemized quote among six they received. They also praised his punctuality and communication through the quote, contract and work. A September 2024 review described an interior railing, newel post and spindles, with an update praising a second project involving basement windows. Other dated jobs include custom shelves praised in October 2023 and exterior trim replaced with composite material in October 2022. In a June 2025 account, Marc replaced an old basement door with a steel door that he cut to fit. A customer writing on Angi in October 2019 described more than 20 linear feet of kitchen crown molding with nine corners, saying he kept both the kitchen and the deck where he cut the molding clean. Google lists a 5-star average from 13 ratings. BBB gives the business an A+ grade and identifies it as non-accredited. Its Massachusetts home improvement contractor registration is active, with Marc Williams named as the registry holder. One older payment complaint deserves its date: an August 2016 Angi reviewer wanted to pay by credit card, said the contractor accepted only cash and checks, and objected to how long it took to cash the check.
I would give Marc 10 out of 10. He install new basement stairs and railings. Marc was great at communicating back and forth. Everything was on time as he stated to us. Marc was very friendly, professional and did a wonderful job at a great price. We are already looking for more projects for him to do for us.
Mark installed new railings on new front stairs. Loved them so much had him change out another set. Will use him for all my carpentry needs. I highly recommend Mark!!
Marc did an excellent job on one of our projects he even worked on the weekend to get everything done which is very rare. We are definitely going to hire Marc for more projects in the future!!
Marc replaced an old basement door with a steel door that he had to cut to size, Came out great! Marc was very responsive, professional and reasonably priced. I plan to use him again for future projects
I highly recommend Marc Williams for any carpentry job you need. I hired Marc to upgrade the wood deck railings to vinyl and add a gate to the stairs. Marc was one of three quotes I received. I went with Marc based on cost, professionalism and when he could complete the job. He began the job as planned and accommodated my changes. He also gave me a referral for power washing and staining which was completed before Marc came back to finish the job. The job was completed and the deck looks amazing. Great job!!
