"Brad Sayre Landscaping surpassed our expectations. They were honest, upfront and fair with the bid and with our design changes/add-ons. They completed the job (with additions) within their estimated time frame. We were happy with the communication regarding our design and planting requests. They took our basic plan and with their expertise, adapted it to our yard with amazing results. The fieldstone walls and the exceptional flagstone staircase are now the centerpiece of our new back yard. We asked for a low maintenance, low water, functional back yard and they knocked it out of the park."

"These guys are the best. Did a partial home repipe of both the water and drain pipes. Other plumbers tried to upsell us by replacing newer pipes and the water heater. Ray and Alex just did the repiping that was necessary. Excellent communication, friendly and on time. Even worked in tough, rainy conditions. Ray owns his own business and takes pride in his work. Recommended him to all my neighbors."

French Drains questions, answered by experts

To clean gunk out of a sink drain, pour in a half cup of baking soda, then 1 cup of white vinegar. The two will react chemically; let them fizz for 15 minutes, then rinse with boiling water. Repeat these steps if necessary for particularly dirty sink drains, and consider a drain snake if there are clogs.

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.

No, it is not advisable to spray pesticides down the drain in your home. Most drinking water and wastewater treatment systems are not properly equipped to remove pesticides. Should pesticides infiltrate waterways, they can cause harm to plants, fish, or other living things. In most areas, pouring pesticides down the drain is illegal due to the potential harm it causes. 

Yes, chemical drain cleaners contain sulfuric acid and hydrochloric acid, both of which are not only dangerous to your health but also extremely caustic. Drain cleaners will corrode your pipes and could lead to destroyed drain lines, especially if the chemicals interact with the piping for long periods. Unfortunately, this extended interaction is likely if you’re dealing with a clog, as the drain cleaner will have just as much trouble as water does moving through your plumbing system.

There are several ways to tell if your gutter downspout drain is backed up. The most obvious sign is when you see water flowing over your gutter edges. This can occur during everything from light rain to a rainstorm. Additional signs can include peeling paint around your downspout, visible dirt around your downspout, and moisture on the side of the house. If you're having ongoing problems with clogs caused by a poorly designed or worn-out gutter system, consider getting a quote for gutter replacement cost.
