"Excellent customer service. Excellent finished product. West Shore Home came to install a shower in one bathroom and bathtub/shower in another bathroom. Their customer service is top tier! They took extra caution to ensure they didn’t damage or disrupt my home or other furniture as they carried their equipment in and out of the house. They encouraged me to see the progress as they worked. (Nothing to hide is always a good thing.) When I expressed surprise and disappointment with one aspect of the design, they immediately began solutioning the issue."

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"2 of 997 Urgent: Project Management Issues & Pending Renovation Work We are experiencing significant project management issues that have caused unnecessary delays and frustration.Their quality of work is good but project management sucks big time,. We started our bathroom rennovations on Nov 29th 2024 the project wsda supposed to be completed in 5 weeks now it is almost 2 months and the master bathroom still needs to begin constreuction. We have had 3 project managers so far. However, despite multiple follow-ups over the past week via our text messaging group and several calls, we have yet to receive any updates on a variety of outstanding work in the loft and guest bathroom that need to be done. This lack of communication and progress is unacceptable. While we understand that Elkay is taking a break, the responsibility for keeping us informed and ensuring the project stays on track should not be neglected. We are not getting proper updates about stataus of several pending issues and we feel like we are being passed around without any clear resolution or accountability. The most pressing concern is the arrival of the bathtub, as all further work on the master bathroom is stalled until it arrives."

Boiler Repair questions, answered by experts

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

A poorly maintained boiler can lead to serious issues like deadly carbon monoxide poisoning, so schedule regular maintenance services. Of course, it’s also a good idea to check your carbon monoxide detectors in your home to make sure they’re working properly. Moreover, when you forget to maintain your boiler, small problems can lead to something much more serious, which will cost you more money in the long run. Repairs average around $400, while a full replacement can total over $6,000.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

HVAC maintenance is crucial for the longevity of your unit. Without proper care, your HVAC unit can break down frequently. In addition, a system that is dirty and not cleaned correctly will not heat or cool as efficiently and will increase your energy bills due to the increase in energy consumption. Additionally, you will probably have to replace your unit sooner than you would if it were properly maintained, which will cost you more money. 

The best way to save money on home heating oil is to get large deliveries in the summer months when the prices are lowest. However, this method will only work if you have a separate storage tank or an unusually large primary tank. You can sometimes save money by opting into a delivery contract, as some companies offer set prices that they believe will sit at the average cost over the contract term. If the price of oil rises, you could enjoy some savings, but keep in mind that you might also pay a bit more if the price decreases.
