Not everyone is good with their hands and that's okay! We're here to help! Ellis Construction & Rehab Inc, can handle everything on your to-do list. Some of our previous customers even call us a Master of all trades because of our ability to handle any project they need. We are Veteran owned and operated, licensed and insured, and our goal is to be your go-to service provider for all your commercial and residential maintenance needs!

"Mr. Ellis was hired to assemble sunroom which he only came out on a Saturday to work on. We thought he was doing ok until we found out he had cut and electric socket in half and never told us, and also left cement all over frame, windows & house from pulling up lenoleum rug he had terribly installed and we told him it was terrible. He agreed and said he would replace it. He went to a carpet store and purchased himself and never came back to install floor. He sent us a text on April 17th and said carpet came in and he would come Saturday morning @ 8am to install the carpet and never showed up or called. My husband called him twice before sending the text with no return call. We sent him a tex on April 26 with no response today. At this point, we do not care for him to return to do nothing else. He left with the carpet not finished, tools to anchor sunroom down, us having to replace socket and light on deck which was also destroyed. Also, one of roof panels he installed in wrong place. Also, the plywood he purchased and installed is already cracking up and needs replacing. Would like to get thhis finished ASAP."

Boiler Repair questions, answered by experts

One of the most common signs you’re dealing with a bad thermocouple is the pilot light for the water heater will continuously go out. For example, you may light the pilot light and then have to re-light it a few days later. You can also look at the thermocouple for a visual inspection. If you notice discoloration, cracks, holes, or other damage, then you know it needs replacing.

Clean regularly, check for leaks, and schedule annual inspections for safety and efficiency.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low.
