"From the first meeting with Ilir Iljazi, I felt at ease. I had multiple issues from trees that damaged a stone wall, stone steps and stone chimney. Punctual, polite, and listens to all of my concerns. Their crew were hard-working, and kept everything neat and organized, and when finished they tidied up the areas and removed all the depris. Every detail was addressed and they worked with the insurance company so their work was paid for in full. Lucky to have found such a wonderful company."

Today I started my stove and stared right up. I highly recommend them and would hire them again."

"I called for a repair to my daughter's roof. The room with the wet sheetrock has a cathedral ceiling with no attic access to determine the source of the leak.

"I was very pleased with the work that was done by this company. Initially I thought that I only needed a chimney cap installed, but after a careful inspection of my chimney, it was found that a crumbling and deteriorating lining of my chimney interior wall had occurred leaving a potentially dangerous situation in my house. I was actually shown the damage so I could determine for myself the extent of the problem. The company installed a new lining and chimney cap in a short period of time, leaving a clean work area. The workmen were extremely polite and answered all my questions thoroughly. I would definitely recommend them for chimney work."

Gas Fireplace Service questions, answered by experts

A liter of bioethanol costs $11 and burns for around four hours, making it cost around $2.75 per hour to keep your bioethanol fireplace running. For comparison, natural gas costs around $0.50 per hour, and propane costs around $1.60 per hour. 

How much it costs you to run your bioethanol fireplace largely depends on how often you use it. Hypothetically speaking, if you run your fireplace for four hours a week year-round, you’ll go through one liter of biofuel per week or about $570 per year to run the fireplace.

You don’t need electricity for a wood-burning stove unless it has a blower fan. Some wood-burning stoves include blower fans to help with heat distribution, but blower fans have a motor and use electricity to power the fan. You can still operate a wood stove without using the blower fan, so it’s a good source of heat if you have a power outage or are looking to lower your electric bill during winter.

Yes, it’s possible to install a wood-burning stove through the wall. The process is similar to venting the stove through the ceiling, but you’ll need to be careful of electrical wiring, plumbing, studs, and other potential obstructions in your walls. If you’re not comfortable with this type of work, call a professional who installs wood-burning stoves.

If you would rather use vinegar to clean the stone fireplace instead of dish soap, this mixture should work fine. Vinegar is slightly acidic, however, so it may etch some kinds of stone without quite a bit of diluting. For a stone fireplace, dilute it to about one cup of vinegar for every gallon of hot water. It’s a smart idea to test the diluted mixture in an inconspicuous area of the fireplace and watch for etching. You can use vinegar to clean quite a few different items around your home, and it’s especially good at removing stains.

Pellet stoves are designed to operate quietly, often emitting only a soft hum from the combustion fan and auger. Compared to traditional wood-burning stoves or furnaces, modern pellet stoves are relatively quiet during operation. This minimal noise ensures they can efficiently heat living spaces without causing disruption, making them a preferred choice for those seeking both comfort and peace of mind.
