"We are very satisfied with the work Premium Drainage & Erosion Solutions LLC have done to our property and house. Over the past four years they have done three major projects for use. The first was replacing our rotting retaining wall and putting in a french drain system for the north side of the house which solved the water problem we had that had rotted the old retaining wall. They also replaced our old privacy fence with a new one. The last project that Adrian has done for us this summer was to fix our roof. Half the wood on the roof had to be replaced and when that was done new shingles were put on the whole house. It has been a pleasure working with Adrian and his crew. We have already been talking with Adrian about an upcoming project for next summer."

"Patrick was professional from the time I reached out up until his arrival at my home. I explained that the control valve from my sump pump seemed to be malfunctioning over the phone, and within a couple of minutes of being on site and verifying the issue, he got to work. About an hour later, he had the part replaced and my sump pump functioning normally and much more quieter than it had been prior. He even cleaned out the basin the pump was sitting in and disposed of the yard debris that crept in. The homeowner and plumbing wisdom that he bestowed on our household was elite as well. Patrick is "our guy"! Thanks Patrick!"

All our of Home Repair Specialists use drop cloths and plastic covering whenever necessary to keep your home safe and dust free. We also do a thorough clean up after every project.

"LFC did a excellent job remodeling my master bathroom. Tony was very patient during our initial consultation and took detailed notes as I described my vision to him. We turned an outdated bathroom into a beautiful spa-like masterpiece. I surrendered a spacious linen closet in the space to get double sinks. We updated the plumbing, floors and cabinetry; added much needed lighting to brighten up the space and found ways to implement space saving features/fixtures for a more efficient use of square footage - the pocket door was a hit. I initially wanted a barn door- I'm so glad Tony convinced me to go with the pocket door. Tony Heard and his team (Omar, Jose, Douglas and Uncle Merc) are true professionals. I especially appreciated the respect and care they took in planning for the project (pre-construction walkthrough, prepping the worksite, daily clean-up, printed schedules, constant communication- and yes he answers email and phone calls) Not only did we (my husband) enjoy having them in our home, our fur-baby terrier enjoyed the daily belly rubs. You won't be disappointed, we have several other projects waiting for Tony and his team."

Boiler Repair questions, answered by experts

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

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.

It can be difficult to determine the cause of a coolant leak unless you have the unit inspected by a certified professional. Most coolant leaks are caused by wear and tear on seals and joints. This typically happens five years after a unit is installed. Additionally, faulty or worn compressors, evaporator coils, and condenser coils can also cause leaks.

If you don't clean a boiler, you may have higher energy bills or no heat. A dirty boiler is inefficient and can't properly maintain a heating system. It may break down more often due to corrosion or clogs from soot and oil buildup. Cleaning a boiler improves its performance. The cost to replace a boiler can be expensive, so keeping it clean is a cost-effective practice.
