"He and his associate were prompt with service, responsible, and trustworthy.  The full bathroom renovation took 2 weeks, and the result was just outstanding.  I would use this contractor again and recommend him to others as well."

"Ken and Eric did a fantastic job of installing the shower surround. They were very meticulous and neat. Made sure everything was done correctly. As far as a luxury bath as a company, the management (Joe project manager) does not care about their customers. They only care about getting their money. They have a three day cancellation contract that nobody reads in the three days and if something is wrong, there’s no way they’ll cancel it they just want their money. They also do not have plumbers that are qualified to move pipes that are in the way so you have to pay more to get that done. Also, in the sales pitch, the salesman (Phil Mahran) tells you that if they find anything behind the existing walls, they can fix it, which is not true they can’t fix plumbing in the way. The company wouldn’t even help pay for the extra plumbing work that cost me $1700."

Customers say: Terrific value

"The Green Mountain Builders team did a fantastic job on my bathroom remodeling project. I had two bathrooms completely remodeled and Steve, the project manager, kept me informed all the way and checked to make sure I was happy with the progress . The main remodelers, Jovon and Al, were outstanding and true professionals as they delivered the new bathrooms exactly as how I wanted it. I would highly recommend Green Mountain Builders to anyone looking to upgrade their home!"

"The job: 2 bathrooms renovated The initial estimate: competitively priced Our initial impression after meeting Sina (1/2 of the partnership with Ali): that we would be dealing with professionals who would be dedicated to high standards of workmanship and commitment to our job….We would later discover that this same dedication and commitment extended beyond Sina and Ali to their entire crew consisting of a painter/spackler, a rug installer, a plumber, and tile installers Our impression as the job progressed: they all demonstrated a pride in their work and personal contribution to the overall project Our overall impression at the completion of the job: from the beginning to end we were very pleased with the overall experience with BAS Construction. The entire BAS team definitely confirmed our initial expectation of high standards of workmanship and job commitment. We would not hesitate to highly recommend BAS Construction for any private or commercial project that you are planning."

"After dealing with roto rooter and Losch plumbing with very bad experiences. Thank God for finding Once & Done. Very professional crew, they did a great job in installing the new sump pump that we definitely needed. Jeff was very honest and nice and explained everything that had to be done in detail. Highly recommend."

Plumbing questions, answered by experts

The lifespan of bathroom pipes is between 20 and 100 years. This is a wide range, so to narrow it down, it helps to know which type of material your pipes are made from. Copper and cast iron have the longest lifespan—between 50 and 100 years—while other materials, such as galvanized steel and brass, last for 50 years or less.

If your sink is on an exterior wall that isn’t insulated, or if pipes travel through a cabinet against an exterior wall that prevents heated air from circulating around the pipes, the pipes can freeze, causing them to burst. The best way to avoid leaking sinks is to insulate the pipes and open cabinets in the short term to warm the water line up and prevent freezing.

Yes, you can fill your toilet tank manually to help it flush, or you can pour the water directly into the bowl to flush it manually. This will work for the majority of toilets, as most use a gravity feed system. However, you should only ever use this as a temporary solution. If your toilet tank isn’t filling, you should find out why. First, make sure the speedy valve connected to your toilet and your water main are open. If that doesn’t solve the issue, call in a professional to address the problem.

There are few things more annoying than trying to fall asleep only to be woken up by the sound of a dripping faucet. If the faucet drips when the water is off, it probably has a loose or damaged seat washer. The screw gets loose from repeated use, making the faucet drip. With outdoor faucets, this is more common in the summer when people are using it more often to water the garden or cool off. Disassembling the faucet and tightening or replacing the seat washer and screw can get the dripping to stop.

How much it will cost to install an earthquake shut-off valve depends on who’s doing the installation. The price of the earthquake shut-off valve itself can cost between $250 and $750, and you’ll pay between $150 and $200 for labor if you hire a licensed plumbing contractor. If you install the valve yourself, you’ll save on labor, but you might need to spend $50 to $300 on the right tools for the job (and it’s a complex job that we don’t recommend DIYing).
