GLOREM is licensed and insured company formed in Maryland in 2010. Our specialty is basement finishing, remodeling and general contracting. We offer quick reliable services that are tailored to meet the needs and wants of each of our clients. Our Quality work and can-do attitude means customer satisfaction every single time. We bring 15-years of experience and offer free estimates.We do professional basements finishing, bathrooms/kitchens remodeling and renovation, LVP/ LVT floors, egress windows, and much more. 10% up to 800.00 off for Angie's List members

"From start to finish, Eugene and his crew were excellent to work with. Our free estimate was much more concise than the "ballpark estimate" thrown out by other companies. While you should always budget for surprises during construction, our estimate was itemized in detail, and showed what upgrades were available and their pricing. The total price was the best of all of our estimates. They worked efficiently, were always friendly, and cleaned up each night before they left. Eugene stopped by frequently to ensure everything was on track and accommodated my suggestions for minor tweaks throughout the process. I very much recommend them and will use them for future remodeling."

"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.

Fire Sprinkler Companies questions, answered by experts

Typically, the white wire is the common wire on a sprinkler valve. This makes it easier to identify, and many local electrical codes require the common wire to be white. However, in some places, any wire can be the common wire. If you ever need to call in a pro for repairs, the industry standard is for the white wire to be the common wire. So, if you decide to switch it up, relay that information to the sprinkler specialist before they start working.

Choosing the right sprinkler heads depends on many factors. You’ll need to consider your sprinkler system’s water pressure (measured in PSI, or pounds per square inch), water flow rate (measured in gallons per minute), and your watering needs. 

Some sprinkler heads, like rotary nozzle and impact sprinkler heads, are best for covering larger lawns, while other irrigation options, like bubblers or drip irrigation, are better for watering prized plants and trees.

Services include running cables, installing outlets, configuring hardware, and testing the network.

You can calculate the number of sprinklers per zone by looking at your water pressure (PSI), flow rate (GPM), and the performance of your sprinkler. Depending on the water pressure, the sprinkler head will use different amounts of water. As an example, at 40 PSI, a rotor head might use 3.5 GPM. If your water capacity is 10 GPM, you can place three heads in each zone. 

Installing a home sprinkler system costs an average of $4,000, with prices ranging from $1,600 to $14,000. It’s less expensive to install a system in an unfinished home ($0.80 to $2 per square foot) than it is to add one to a finished home ($2 to $7 per square foot). Sprinklers are also more expensive to install in high-rise buildings, for which you can expect to pay a minimum of $4 per square foot.
