Dependable Chimney Waterproofing Services In San Antonio, TX

The changing weather conditions in San Antonio can take a toll on chimney masonry over time. Rainfall, humidity, intense sunlight, and seasonal temperature fluctuations can allow moisture to penetrate brick and mortar surfaces, leading to costly damage if left unprotected. Our chimney waterproofing services help homeowners safeguard their chimney systems against moisture intrusion and premature deterioration.

At San Antonio United Home Services, we use high-quality waterproofing products specifically formulated for chimney masonry. These breathable sealants create a protective barrier that helps repel water while allowing trapped moisture within the masonry to escape naturally. This process helps maintain the integrity of the chimney without causing internal moisture buildup.

Before applying any waterproofing treatment, our technicians perform a detailed assessment of the chimney structure. We inspect brickwork, mortar joints, crowns, flashing, and other exposed components to identify vulnerable areas that may require attention before protection is applied. This careful preparation helps maximize the effectiveness and longevity of the waterproofing treatment.

Our goal is to help homeowners maintain stronger, longer-lasting chimney systems. Proper waterproofing helps reduce future maintenance concerns while supporting the overall condition and appearance of masonry components for years to come.

 Trustindex verifies that the original source of the review is Google. After weeks of clothes taking forever to dry, I called for a dryer vent inspection. The technician found and cleared a major blockage. He explained how dangerous it could’ve been if we waited any longer. Grateful for the quick response.

 Trustindex verifies that the original source of the review is Google. United Home Services has replied to my posting of my alarmingly shocking experience with two of their employees in December 2024.  I want to assert that every word I wrote was the absolute truth.  I did not fabricate, exaggerate or invent any of it.  I can understand that UHS management is having trouble believing all this happened because it was so bizarre and strange.  I am a senior citizen and veteran and have lived all over the country and the world and have never ever been the target of such unprofessional, threatening, and intimidating behavior from any contractor.  I think UHS's response is to completely 'dis' my posting:  disregard, disrespect, dismiss and disparage, but it is UHS that needs to have a good look at the  behavior of its badly-trained employees.  Again, these 2 low-lifes showed up not in a company van (as per UHS's website) but in a private pick-up truck, a grey Chevy Silverado (I also have the TX license number) with NO LADDER, no drop cloth, a small bag with one thin, scrawny brush that did not reach up into the chimney, NO FLASHLIGHT, no written report of work done, no receipt book, no MANNERS, absolutely no identification, no pocket badges, no neck lanyard ID cards, no monogrammed caps and shirts, nothing.  I'm still very angry with myself that I let them in my house.  I was foolishly trusting.  "Tony" fabricated a false inspection when he said my chimney needed repair although he had no ladder to get on the roof.  He just made it up!  It was a con to get me to pay for unneeded repairs.  When I protested at the overall poor, unprofessional service, Tony became extremely abusive and threatening.  He yelled at me to pay him in cash, "you pay, you pay now, now you pay,' he shouted on my front steps.  Even if I had given him cash he had no receipt book or electronic device to record the transaction and no way to calculate TX state sales tax.  He lied when he said that United Home Services was 'his' company, he 'owns' the business.  When he failed to bully me into  paying for very bad service he threatened me that he was 'going to put a lien' against my house.  Imagine, how very stupid can any con man be?  UHS is attempting to disparage my experience by suggesting that I have made some sort of racial slur against Tony, but it was Mike, Tony's boss, who told me, volunteered to me, that "Tony's from Israel" as some sort of lame excuse that because Tony's 'new'  he doesn't know how to behave as a professional.  Anyway, Israel is not a race; it's a sovereign nation.  Tony's origins were never an issue with me; his unprofessional, abuse behavior is.  I was so alarmed by Tony's behavior I reported this incident right away to all the right people and institutions:  TX Attorney-General, Consumer Protection, the BBB and the local police department.  I still feel so strongly about this abusive incident that I am prepared to stand up and testify in a court of law, should it ever come to that.  UHS's 'quality customer interaction' is a load of pure hogwash, to put it politely.  I've already had a 'direct conversation' with the company on the day of the incident and the manager, Mike.  They are not 'here to help' but to white-wash extremely bad service.  Consider the risk I have taken to publicly report this:  your threatening, intimidating, bully employees know where I live.  I'm a possible target for further abuse or revenge.  That's why I'm glad to have reported this incident to the local police.  Also, consider how very frightened and scared I was when Tony raised his voice in a hot temper:  loud, aggressive, rude,  vulgar, disrespectful, enraged that I was not handing over $99. in cash.  Like it or not, I regard my public posting a civic responsibility to warn and protect others who might fall under the 'special' chimney deal of United Home Services.  I absolutely stand by my first posting, every word of it.  I am gratified to think my speaking-out benefits others.  Good for Google for making this service available.  Thank you Google!

 Trustindex verifies that the original source of the review is Google. Our chimney was leaking smoke into the house. United Home Services diagnosed a crack in the flue and repaired it the same day. The experience was seamless and professional from start to finish.

 Trustindex verifies that the original source of the review is Google. The air duct cleaning service was outstanding. The team took their time, showed before-and-after images, and left our home cleaner than they found it. I highly recommend this company if you care about the air you breathe.

 Trustindex verifies that the original source of the review is Google. I didn’t realize how outdated our fireplace setup was until the technician came in for maintenance. He not only cleaned it but also performed a few essential adjustments that made it look and perform like new again. Very satisfied.
