Locktight Masonry & Waterproofing is a Watertown contractor listing masonry, concrete foundation repair, French drains, and waterproofing services. The profile shows 3.9 from eight reviews, six years in business, 28 projects, Spanish support, and a Massachusetts license claim expiring October 7, 2026. Six visible 2024 reviews praise chimney repairs, foundation crack repair, masonry, drainage work, communication, prompt service, and reasonable or competitive pricing. Two detailed reviews from December 2024 and January 2025 allege an unfinished bulkhead job, unnecessary trench and foundation work, attempted high-cost stabilization, property mess, and repeated failure to respond. Before booking, obtain an independent foundation assessment, verify the license directly, require a written scope and payment terms, and clarify warranty and permit responsibility.
Locktight showed up at 8 am and wanted a local personal check of 2750 dollars - not a credit card as shown on Angi - to buy new bulkhead. They came back - no new bulkhead - tore out old bulkhead and steps and dug a trench around the side of the house, saying there cracks in the foundation and they would need $30,000 - $40,000 to stabilize the house or it could be condemned. I would need to sign a waiver if I didn't agree . I said I needed a second opinion and also would contact the Building Commissioner to see if Locktight had obtained a permit, as they indicated they had. They asked if I wanted the trench filled back in - I said no, as I needed verification from the Commissioner on the cracks status. They left - didn't take the old bulkhead, leaving me with a huge mess. The Building Commissioner came out that afternoon and said the foundation was fine. He tried contacting Locktight twice the following day and they hung up on him. My attempts to reach them were similar - voicemail or hang ups.. My new contractor is charging me $6200 - a lot of his time is being spent on filling back in the unnecessary trench work.
Locktight Masonry and Waterproofing is a scam outfit! A quoted $5500 bulkhead door replacement turned into a huge messy trench and an attempt to extort $30,000 - $40,000 for unneeded foundation stabilization.
Guys were very professional, did a great job, they installed chimney liner, cap and repaired the exterior bricks of the chimney. Awesome job, and best of all no surprises in the cost, what they quoted me is what I paid. I would definitely recommend them!
Do not look any further for a masonry company! James and his workers are the best! The job was completed on time and the cost was very reasonable. There was excellent communication throughout the project. The result was better than expected. I plan to have my front steps repaired after the winter, so I will l definitely be giving James a call in the spring
Mike and his team were exceptionally professional. Service is always prompt, and they constantly go above and beyond to ensure that all the water draining problems are resolved. Fees are also as competitive as they get. Would definitely recommend their services to anybody who needs a problem solver
