"Zarco (Legacy Pool Service) really saved me after my original hire to close the pool ghosted me. Leaves were starting to pile up and I needed to get someone quick. They squeezed me in less than 24 hours after contact and did a flawless job closing my pool. They were on-time, quick, thorough, friendly and did the work at an excellent price. Couldn’t be happier and I now plan to use them for my opening as well. A++"

Beltway pools was established with you, the customer, in mind. Our goal is to provide the most personable, straight forward service while raising the industry standard on communication and relationship building. We are members of the same community we serve, so we prefer to treat you like a neighbor instead of a number.

" I am paid more than 80k to redo my pool house located in Mclean, VA. The pool never worked. Always green. Every time you call, they will send one cleaning crew for 180$, but the answer from them was that the pool will be better after a few days. After a few days, the pool is green, and you call again, and they will say our pool needs multiple cleanings, and they will do various cleanings and send various invoices. When cleaning, they say the pool will improve in a few days. After a few days, if you call to ask why the pool is green, they will say it's one more service. This pool was reconstructed, and the same company did the plumbing and machines. Please be careful when hiring this company complete rip-off. After ripping off, they will say customers do not know anything about the pool. This is the value they will give to the customer who paid around 80k "

"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence. Time sensitive materials which added to homeowners to-do list. Gave this contract to LF on the surface of their history and appearance of a 'good local company' but should have stayed with original contactors in VA. Puddle of water forms when it rains"

Daniel started his construction career in 1983 as an apprentice in Switzerland, Europe. There he learned from experienced old school carpenters how to timber frame and build log houses. Cutting mortise and tenons for structural posts is still something that's done today. Since the late 80's, Daniel has learned all about the ever-changing U.S. construction industry. Daniel started his own remodeling company in 2001 and has since designed and built many additions and remodels in and around Montgomery County, MD. Due to years of experience, Daniel is able to make design changes that make construction easier and cheaper. He has proved himself to be a great communicator so that all parties involved in a remodeling project work as one. His ability to plan, schedule, and execute projects have made jobs less stressful and more rewarding for his clients. Things most frequently mentioned in client reviews are that Daniel and DK are staying within budget, getting the job done on time, are responsive and available, have clean and organized job sites, and are experienced.

FAQs for swimming pool cleaning and maintenance service projects in Gaithersburg, MD

No. Salt water pools add chlorine to your pool using a sanitation system that produces this chemical. Salt alone does not sanitize a pool.

For pools with no salt, you need to add 30 lbs. of salt for every 1000 gallons of water.

Over-salting your pool won’t damage the pool system, but it will create water that tastes salty. This can also damage metals such as ladders and handrails.
