At Integrity General Construction, I pride myself on 4 main values. First, honesty is uncompromisable as it is the foundation of trust in business and precedes any opportunity to make money. Second, my priority is to complete any project according to your specifications. I am not satisfied until you are satisfied. Third, I value and respect your time and privacy. I understand that it is a privilege to be hired by you and refuse to waste your time or infringe on your privacy, hence the establishment of trust first. Lastly, but perhaps most important, I value integrity - doing the right thing even when no one is watching. These 4 pillars of business combined with my experience and qualifications make two things certain: a job well done and which contractor you choose for your next home improvement project.

"His work was great except that he never shimmed up the windows sill, which left a wide gap between the sill and the windows trim. After paying $360, I must now fill those 4 inch wide gaps with 1 bys, Bondo and caulk. I feel at age 77 I shouldn't have to water proof the window sill myself. Reagan takes pride in his work but I feel he made a mistake on this job."

French Drains questions, answered by experts

It is not advisable to use drain cleaner in a washing machine. Drain cleaners contain harsh chemicals that can damage the internal components of your washer, including rubber seals, hoses, and even the drum. These chemicals can also react with any residual detergent or fabric softener, potentially leading to noxious fumes. If your washing machine is experiencing drainage issues, it's best to address the problem directly by inspecting and cleaning the lint filter, checking for clogs in the drain hose, or seeking professional repair services. Using drain cleaner in a washing machine is a risky solution that can cause more harm than good.

Professionals use snakes, hydrojetting, or chemical cleaners to clear blockages effectively without damaging pipes.

Regular maintenance, such as not disposing of grease or coffee grounds down the sink and routine use of strainers, can prevent clogs.

Once you’ve poured the baking soda and vinegar into a drain, you should wait about 10 minutes for the mixture to break down the clog. If you try the baking soda and vinegar method and it doesn't work, you can do it again or try the baking soda and salt trick.

Yes, you can pour water down the toilet to help it flush. For each flush, you’ll need 1 to 2 gallons of water for newer toilets or 3 to 5 gallons of water for older toilets. Rather than dumping the entire bucket in all at once, pour the water in slowly for the best results. If you’re pouring water down the toilet to help it flush after a clog, only use 1 gallon of hot water.
