Guimauto Construction is a Hudson-based exterior contractor — siding, roofing, gutters, decks, windows and doors — founded by Tullio Guimaraes after his own start in the U.S. construction industry, with his wife Natalia Guimaraes running the financial side; the company describes itself as family- and immigrant-owned. Its Massachusetts home improvement contractor registration is active, and Better Business Bureau gives it an A+ letter grade. Siding work is where the record is deepest and most consistent. Across dozens of reviews from 2024 through this August, homeowners describe vinyl and shingle siding jobs finished on schedule by crews reviewers repeatedly call attentive and courteous, often naming specific team members — Esther, Carlos, Mauricio, Joao, Rogerson Soares and others come up by name across different projects. Customers also describe gutter installs, deck builds, porch and railing work, and window and door replacements handled with similar care, several noting the crew caught and fixed mistakes left by other trades on the same job. The record isn't spotless, and the two most recent negative accounts are worth reading closely. In a June 2026 review, a customer described a botched gutter and fascia installation — wrong materials used, resulting in a poor-quality job, with nails and construction debris left scattered on the property. In a July 2026 review, another customer said that despite the company's reputation for good communication, they had to repeatedly reach out themselves to get any update on where their project stood. Those two accounts sit alongside other reviews from the same stretch of 2026 describing the opposite: clear notice of schedule changes and workers showing up exactly when promised. For siding, roofing, gutters, decks or exterior window and door work, this is a contractor with a long, mostly strong track record and real family ownership behind it — but the recent gutter complaint in particular is worth asking about directly if that's the specific work being considered, and it's worth getting a clear commitment on project updates before signing, given how differently that went for at least one recent customer.
Great company. The team shows up exactly when they say & if there are any change orders they’re clearly communicated and transparent.
I am very happy with the results in adding New Vinyl to my house and upgrading my porch. The team addressed all my concerns timely and to my satisfaction. Thank you for that!! We never have to paint again! It looks like a brand new house!! Great work!!
Disappointing experience. While they have great reviews that boast of timely work and excellent communication, this wasn’t my experience. To get any updates on my project, I had to reach out. They didn’t let me know what was going on or when I could expect workers to be there despite asking for a schedule of when work would be completed so I could plan around it. My siding project took 4 weeks because they missed days, came late, and sent a tiny crew of 1-2 people most days. The workers left nails all over my walkway and steps instead of cleaning up at the end of each day. They did not properly tyvek my house after removing my wood shingles to protect against rain, and they installed the siding with no insulation underneath, so I expect my heating bills to go up dramatically this winter. The office speaks some English but not a lot, and the workers don’t speak any, so good luck getting your questions answered or concerns addressed. The finished work looks good, but it was a stressful and disappointing process to get here. I wish I had sprung for a more expensive company that operates like professionals and treats your home with respect. I don’t recommend this company.
Guimauto is an excellent construction company. I am extremely pleased with the siding job done for me, work was done in a timely manner. Workers were knowledgeable and extremely courteous, I would highly recommend this company as they deliver quality results.
All around wonderful experience. After receiving quotes for new siding from a few other companies, I felt confident going with Guimauto from start to finish. From communication, efficiency, and craftsmanship, Guimauto checks all the boxes. Any questions or issues I had were handled promptly and thoroughly. I would gladly recommend Guimauto to others, and will absolutely be contacting them for other projects down the line. Super nice team, and super great work!
