"I hired Highlander to install a channel drain in front of garage to keep it from getting water in it. The guy showed up with his 16 year old son and dug the trench and laid the pipe very shallowly and left a large open hole in front of my driveway, that was one issue. The second issue was there was no slope to to the pipe. It is straight so the water is not actually draining. The third issue was they cemented the grates onto the the channel drain when they are supposed to be removable so you can clean it. They did correct that and the hole near the driveway they patched with stone, but it is still not pitched properly and the concrete was cracking almost immediately after drying, I asked for the salesman to come back and look at it and asked him if it looked professional, because it didn?t to me or my stepfather who does concrete for a living, and his response was that it did. Well, less than an a year and grates are popping up because the concrete is completely cracked."

"We originally reached out to Nick based on a referral. As new homeowners, it was important for us to find someone that we felt we could trust, and we found that to always be the case with Nick and his team. They made the entire process far easier than we ever imagined a kitchen remodel could be. Nick is professional, organized, communicative, honest, and went above and beyond to make sure that we were happy with every element of the project. We LOVE our new kitchen and felt that the team really delivered the highest quality services while being very reasonably priced compared to other quotes that we received.

Boiler Repair questions, answered by experts

Attempting DIY fixes can be dangerous. Regular boiler maintenance can help prevent overheating, so schedule professional servicing as a preventive measure. In an emergency, telling occupants to leave the house is a good idea. Then, you can turn off the boiler and the gas or fuel supply. Let it cool naturally, and check the thermostat's settings. Ensure there are no obstructions around the boiler for proper ventilation. Monitor the pressure gauge; if it's too high, bleed the radiators if necessary. During this time, bringing in professionals for troubleshooting is also smart.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

Generally speaking, yes, turning one radiator off does save some money, especially if the system is a little older—so long as you’re not cranking up the dial on the ones you leave on. But some HVAC specialists argue that keeping your entire system on ensures that your boiler stays efficient. After all, it’s rated to fit your home and heats the amount of water your heating system needs. This could be the case if you have a new system. However, turning radiators off in unused rooms lowers the amount of hot water you need.

Signs of needing a new expansion tank include visible leaks and a dull sound when you knock your knuckles against the tank (working tanks should sound hollow). A malfunctioning tank may also sweat with condensation, cause pipes to create loud noises when the system is turned off, and lead to very high-pressure readings on the boiler’s gauges. When in doubt, call for a professional inspection to find the source of the problem.

Addressing banging, clanging, and hissing radiators involves several steps. Start by bleeding the radiator to release trapped air, a common source of noise. Next, ensure all valves, brackets, and pipes are securely tightened to prevent the components from rattling. You can also consider installing radiator insulation to dampen heat expansion sounds. If you perform all of these fixes and the noise persists, explore the use of radiator additives that can mitigate water-related noises. If all else fails, you should consult an HVAC professional.
