SLA Construction is a Milford outfit that's been doing business since 2014, according to its BBB file, and its work leans hard toward decks — Houzz lists 'deck design' as its stated specialty, and most of the nine projects shown there are decks, sheds and porches. In 2019 reviews, homeowners describe Greyson Lima replacing an old deck with a new one that came in within budget, suggesting upgrades for a longer-lasting build without pushing for upsells, and installing a Trex deck with white railings, working through a Sunday to finish and improvising a cost-effective fix for an old storm door. One thing to confirm before hiring: the state's home improvement contractor registry lists SLA Construction's registration as revoked. Its BBB file, separately, carries an A+ rating, though the company isn't BBB-accredited. Worth a call for a deck build, but check current registration status directly with the state before signing anything.

SLA Construction replaced my tired old original deck with a beautiful solid deck that was within my budget. Greyson Lima made recommendations to our plan to make the deck nicer and longer lasting, but within our budget. He did not pressure us to go his way, but made suggestions based on prior work. The materials they used were top quality and we feel we got a better deck than we planned. Greyson and his team were on time and completed the job in the expected time. They were very respectful to my wife and I with regard to schedule, cleanup and general conversation. I would hire SLA for future projects.
SLA construction installed a beautiful treck deck with white railings. They worked quickly and tirelessly, even on Sundays to complete the work. They also were creative when trying to come up with cost effective ways to replace a very old storm door.
