Q: How do I easily access my drain valves?

• <div><p>You may have to dig out drain valves if they are buried under dirt. This method isn&rsquo;t ideal, and it increases the chance of clogs and damage. Ideally, a drip irrigation system buries drain valves in a gravel pocket so they are easier to access and better-protected. If you have trouble accessing drain valves, hire a sprinkler professional to find them safely and efficiently.</p></div>

Q: What causes a basement to smell musty?

• <div><p>Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that&mdash;like installing air fresheners and a dehumidifier&mdash;can help keep musty odors from returning.</p></div>

Fast and efficient service from coming to quote the job to scheduling and completion. A leak developed but the crew returned within a reasonable amount of time to diagnose and correct the problem. I highly recommend Gutters By Design.

We were in dire need of a new roof, and contacted several roofers. Most didn't even return my call. A couple other contractors said they'd come out and do an estimate, but never showed up. Then we found Leneva (Corey Garza and his crew) -- what a breath of fresh air! He immediately...

He started with a price of $380 which was a bit high and then he said he found another problem after he started. Now it is $500 dollar repair on an $800 six yr old fridge. I could have spent another $400 and had a new one. Will not use him again.
