    I've been using Ken and his team for several years after a referral from a friend. They have been…read moreprofessional, reasonable; informative, helpful, and have proven work. I recently decided to try replacing my very old sink disposal that was making a loud grinding noise. It was at least 30 years old so I wasn't surprised. The repair was surprisingly easy as I used the same brand to replace and the flange is the same after decades so I didn't need to do the hard work of interacting with the sink itself. When I pulled out the old unit, sure enough there was Ken's sticker on it from when he installed it for the prior owners of my home decades earlier! It was so old it didn't have an area code needed. Ken's team also told me about some repairs that could be safely deferred and done with the help of the local town when they did other repairs they are responsible for, which saved me about $1000. Tip: visit the Absolute website as there are usually coupons available to reduce the service charges.

    I have to upgrade my experience. Since our first encounter with Absolute, we had a couple new…read moreissues arise and they were the first ones I called. The first one was a leaky radiator pipe in our bedroom which they were able to fix quickly and saved us from having a major problem if the leak continued and or if the pipe outright busted. The technician also noticed a problem with our water tank and gave us suggestions as to how to fix it. I gave him the green light and he was able to do everything in one day which saved time and rescheduling costs. This past week, I asked them to do what was supposedly a quick and easy faucet replacement in a bathroom sink but it turned out to be more complicated than expected. Bryan and very good in explaining everything and getting all the repairs done. So, after using them 3 times and been extremely satisfied with the results, I felt that I needed to upgrade the number of stars to reflect how much I appreciated their time, work, professionalism and helpfulness. I hope to be able to keep this relationship going when other projects arise.

    We're a small collective that shares stories from freelance and contract workers who've been…read moretreated unfairly. This is one of those stories. A contractor was hired by this company to build a fully functional website on a rushed timeline. They were told they were the only person working on the project, and that the urgency was due to the company's former developer being in a legal dispute and planning to take down the live site by June 1st, 2025. The contractor dropped everything to help and finished the site two weeks before the deadline. Over the course of several weeks, the contractor even went to their office multiple times for meetings with the owner's son and other team members, working in good faith to move the project forward.After the work was done, it came to light that two or three other people were also working on the same site, despite the company claiming otherwise from the start. When the contractor followed up for payment, the owner's son who was the main point of contact allegedly said "My boy could do it for less than $1,000, so our initial agreement on price is gonna be a lot less now." He also added he was going on vacation in 15 days and "didn't have time to deal with it." All this while wearing an expensive Rolex. The contractor was told, "Send me the invoice I'll pay you for your time." The invoice was sent immediately, and the son followed up once more saying, "I'll get back to you." After that, he went completely silent no reply, no payment. The contractor was left dismissed and disrespected. The stress and anxiety from this on top of an existing heart condition led to serious mental and physical strain. Legal steps have since been taken. This post is meant to warn others if you're a freelancer, contractor, or subcontractor, be cautious. Get everything in writing, and don't ignore red flags. No one should be pressured, misled, ghosted, or lowballed after showing up, putting in the time, and delivering their end of the deal.

    I have used Rich for over 10 years for various plumbing needs, including water heater…read moreinstallations. Rich is a real professional who not only loves what he does, does it well, but also really cares about his customers. Last night, my water heater kicked the bucket. I called Boston Water Heaters at around 9 pm to leave a message and Rich answered. Yes, he answered at 9 pm. Rich fit me in and came out today to install a new water heater for me. He came when he said and charged me what I knew to be a fair price. I will not use anyone else for this service. The care he has shown to me when I've been in a pinch has earned him my loyalty as a customer. Thanks Rich!

    I called Rich at the beginning of December to talk about replacing my ancient (1982) furnace and a…read morewater heater that was starting to hurt. Add in that I was trying to do it through Mass Save with a heat loan. Rich came out to my house on a Saturday to look at the job and give us the quote we would need to get the heat loan. He had the quote to me that same day via email and he dropped off a paper copy the next business day. He's forthright and honest and he started teeing up the special pieces we would need while we were waiting for the bank to approve the loan. He was very responsive the whole time and was good about giving me a call for updates. Because of the jury-rigged nature of the old furnace, he told us it would take two days, possibly three, to get the old one out and the new furnace and water heater in. He got the water heater in and running on day one so that we could use it. He worked late on a Friday to get the furnace done right before the temperatures dropped down below 20. The new ductwork, venting, and drain for the condensate are all really well done. You can see the quality of his work. It is well below freezing outside, and this is the warmest my house has been since I bought it. He even came back after the install was complete to change an exterior fitting for the air intake because he wasn't happy with the part he had on hand when he did the job originally. 10/10 I would go back to Rich for any work I needed done.
