"Repair Service to Fix Gas Boiler - WM Henderson first sends out a tech who is not familiar with gas boilers and admits there is an issue but does not know how to diagnose it. I had to pay $89 for this. Instead of having the right person come out, I had to to actively call again to get someone else to come out. The 2nd tech diagnosed the issue, but wants to charge me the same $89 that I already paid. - and quotes me $380 for the repair - and has to order the part. I agree and then call back the next day to confirm part is on order - and they tell me the charge is $1,015. I asked to speak to a manager to discuss, and no one is available and no one calls me back. I bought the replacement part from a supply where house (confirming it works with my make/model of boiler) and it cost me $165. I have had other scheduling issues with them as well. Don't use them!!!!!!!!"

With over 15 years of experience, Keystone Building Services LLC can handle any or your home or business remodeling and repair needs. Call Justin today for your free estimate!

"We are extremely pleased with Keystone Building Services' (KBS) work on our home. Projects were fairly priced; I got other estimates. My roof didn't need replacement, yet rainwater was leaking in my LR. Justin was able to troubleshoot & seal several points on the chimney allowing leaking - stopping the problem. After another Angie's List contractor told me my next project couldn't be done because of joist spacing; KBS came to the rescue. My HVAC unit access was in the ceiling of my BR closet. KBS cleverly saw a way to get access constructed in the adjacent hallway ceiling. The framing blends in perfectly with the other molding. KBS does an excellent job of cleaning up other contractors' messes. After another contractor overcharged me for an incomplete basement drywall demo, mold remediation and poorly done French drain rehab, KBS: located & remediated mold in in another section and improved the water drainage. We're already planning future projects for KBS. "

Percolation Tests questions, answered by experts

Clear the area for access and inform the testing team about the building’s history and renovations.

More than likely, you will not notice exposure symptoms for quite some time, which is one of the reasons why asbestos is so dangerous. Shortness of breath, persistent coughing, chest pain, and other respiratory symptoms are signs of severe asbestos poisoning that typically lead to more dangerous conditions, such as mesothelioma, asbestosis, and other forms of lung cancer.

Whether or not to buy a home containing asbestos is ultimately a decision for the homebuyer, and there are several things to consider. When in good condition and contained, asbestos is unlikely to present a health risk—it’s when those tiny fibers are loose and airborne that they become a problem. Consider any renovations you plan on doing to the home that could disturb existing asbestos and the cost of removal. If an inspection finds asbestos in a home on the market, you could negotiate with the seller for a lower price, though this isn’t a sure thing.

Professional testing is advisable to ensure safety regulations are met, and accurate results are obtained using certified methods.

No, but it’s common that they do. Gravity furnaces weren’t terribly efficient so wrapping either the ductwork in asbestos, the furnace itself, or both, was something done regularly. This allowed the system to retain more heat. At the time, this greatly enhanced the efficiency of the furnaces but it wasn’t until later that we became aware of just how carcinogenic and dangerous asbestos could be.
