"I would highly recommend Chris and his team. We were looking to redo our front landscaping and fix the grade so that water would drain away from the foundation. We solicited a handful of bids and what set Chris apart was first and foremost his responsiveness and that every communication was focused on making sure I was happy and we were on the same page. Additionally, he was able to take a design we received elsewhere and make it work within our budget. Him and his team showed up on day one to work and every member of his team was kind, respectful, and focused on making sure that I was satisfied with every inch - the attention to making sure the customer was satisfied throughout the process was impressive. They were extremely collaborative and flexible as tweaks were made and I couldn’t have been happier with every step of the process. Again, I would highly recommend Chris and his team for your landscaping needs. He changed the look of our home and we are truly mesmerized."

Our neighbor highly recommended Atlas, and we see why!"

Transform your outdoor space with Finishing Touch Landscape Co LLC. Our expert team in St. Louis specializes in landscape design and hardscape installation. Let us bring your vision to life and create a stunning oasis right in your own backyard. Contact us today for a consultation.

"Finish Touch gets 5 stars from me. They built us a beautiful looking retaining wall at the rear of our house 4 years ago this month and were the low bidder by far--the bids ranged from over $17,000 to under $3000 for Finishing Touch with several others from 6k to 10k. I waited to post a review until now because build quality of a retaining wall can't be measured until after passage of time. Their wall has held up nearly perfectly over 4 years now so I believe it is justifiable to say it was properly built and the preparatory pre-construction work like ensuring drainage was all done well. On top of doing first rate work at the low price, a few months ago I contacted Mr. Watson about another potential job involving our crumbling and sagging concrete front steps and porch. He spent a good 20 minutes+ explaining we could get 90% of the benefit of redoing them by instead mud jacking them and using polymeric sand to fill a crack. He was right. I unreservedly recommend them."

Foundation, basement or crawlspace waterproofing / encapsulations FAQs

Cleaning your crawl space is a worthwhile investment for several important reasons. A properly maintained crawl space prevents structural damage by eliminating moisture that can deteriorate wood supports and metal components. It also significantly improves your home's indoor air quality by removing allergens like mold spores and pest droppings that can circulate through your living spaces. 

Additionally, a clean crawl space contributes to better energy efficiency by allowing proper insulation installation and reducing humidity levels that force your HVAC system to work harder.

Several warning signs indicate your crawl space needs professional attention. Look for musty odors throughout your home, unexplained increases in allergy symptoms, higher energy bills, visible pest activity, or moisture issues. 

Other indicators include sagging floors, warped wood, visible mold growth, standing water, or damaged insulation. If your crawl space hasn't been inspected in over a year, or if you've recently experienced flooding or severe weather, it's advisable to have professionals assess the space even without obvious symptoms.

Most crawl space cleaning projects take between one and three days to complete, depending on several factors. Simple debris removal in a small, relatively clean space might be finished in a single day. 

More involved projects that include mold remediation, water damage repair, or pest control require two to three days. For large crawl spaces or those with extensive contamination, the timeline might extend to a week, particularly if additional services like encapsulation are included in the project scope.

You can remain in your home during basic crawl space cleaning. However, if the project involves mold remediation or pest extermination with chemical treatments, temporary relocation might be recommended, especially for household members with respiratory conditions or chemical sensitivities. 

Professional cleaning companies use containment procedures to minimize the spread of dust and contaminants into living spaces, but some disruption is inevitable. Discuss your specific situation with your service provider to determine the best approach for your family's needs.
