Nicholas J Walsh's Massachusetts home improvement contractor registration, number 189046, is expired on the state registry.
Nick and his team do an amazing job. From start to finish they are communicative and dilligent. They tackled a basement remodel and bathroom addition. He was excellent at not only the craftmanship but the coordination and project management of subcontractors. Would absolutley reccomend NJW to anyone in the area and we will be only using them again in the future for projects.
I spent a year trying to get a wall repaired due to severe, long-term water damage. Every other contractor and repair company I reached out to would waffle about until they disappeared. Nick and NJW Construction was quick to respond, they were able to squeeze our job in to their schedule, and finish up in just a few days for half the price that anybody else gave us. Not only that, Nick and his team were extremely thorough in fixing the damage, remediating the source of the damage, and testing their work to ensure that the damage would never happen again under even severe weather conditions. Absolutely top-notch work start to finish. 1,000% recommended.
I had a kitchen and bathroom done by NJW Construction and couldnt as for a better job. Told me what had to be done and in what timeframe it would be complete.
Any project is nerve-racking in the beginning. Finding someone who is dependable, extremely professional, with great work ethics is hard to come by.
Very professional, did a great job would most definitely recommend them to others. I would also use them again.
