ARE YOU READY FOR A BETTER CONTRACTOR? Keystone Basement Systems is the leader in basement transformations, providing personalized, guaranteed solutions for water intrusion, foundation repairs and the creation of functional, beautiful living spaces. WE WILL NEVER PRESSURE YOU! If you are looking for a solution designed by the industry experts, we can help. GUARANTEE “We Warranty Our Systems, We Guarantee Your Satisfaction!”

"Select another company or hire someone to redo your driveway instead. It'll take 1/4 of the time to schedule, reschedule, and complete the project, and you won't have to deal with all the messes and damage they leave in their wake. While Keystone's sales team does a great job selling their leveling service, delivery and scheduling are abysmal. It takes months to schedule, followed by weeks of equipment failures and rescheduling. You'll also be cleaning up stains and messes left behind, reminding them of what has and hasn?t been done yet, as well as essential contracted items and processes that were skipped throughout. You can call and discuss the issues with the crew and management, but only if you can actually wade through all their random phone numbers and find someone willing to answer or return your calls. For tens of thousands of dollars, you expect a simple level of service, coordination, and professionalism that doesn't follow through from sales to crew. "

"This is the second time I’ve used Advanced for my basement waterproofing needs and they were again fantastic. Work was done well and it was easy to schedule. They are low pressure so if you have a project and just need to get an opinion, reach out to them. Chris is great and very attentive and helpful. Both of my waterproofing jobs still cost less the the initial job from one of the big companies, so I was really pleased with their work and price. They did a nice job cleaning up (but concrete dust gets everywhere so I still have work to do). Highly recommend!!!! I also live in a township with strict permit codes and they knew to check and help with that process (the other company did not)."

"My wife and I were very pleased by the plaster work that was performed in our home by Robert Dell'aquilla Plastering. The owner and his workers did great work on about 5 different areas of our house, ranging from holes that had been punched into walls from previous electrical work, damage that had been done during storms and leaking gutters, and cracks in some rooms due to subsidence. In each case, the work was done professionally and completely, addressing the issues and leaving each area looking like new. The employees were very experienced and skilled, making some difficult repair situations look amazing. They treated our home like their own, even repairing some minor issues they spotted that were not initially requested. All of the crew were diligent in cleaning the rooms and closet areas that had been worked on. We found Robert Dell'aquilla Plastering by searching and researching previous reviews. We were very pleased with the work that they performed in our home."

"We knew actions needed to be taken quickly to prevent mold. Jeff had his crew, including Greg, in the house quickly. They ripped out the soaked carpet and padding and disposed of it; they removed standing water; they brought their equipment in to start the process of drying out the basement; then they sprayed an antimicrobial solution to prevent mold. Every step was handled with the least amount of disruption and in a very professional manner. ServPro was the calming force in this horror story…….anytime we called Jeff with a question, he had no hesitation taking the time to thoroughly answer our question. We are extremely happy with ServPro. We hope we are never in the position again where we would need their services, but if we are, we would not hesitate to call them.

"We had our basement waterproofed by Baker's. It's been bone-dry since. We did have one piece of equipment fail within a month of the installation, but it was a third party dehumidifier that was just a dud I guess, no fault of Baker's. I texted the project manager about it on a Sunday. I expected a response the following week. He got back to me within the hour. The equipment was removed and replaced within a couple days. Everything great since. I would highly recommend Baker's, but specifically our project manager Nathan Goddard and the head guy on site Daylan. Can't remember his last name, but he's got a long beard and did a great job. Thanks to both of them and the rest of the guys."

"Terrible: 1) Installer did not install as agreed upon. Line was to be placed behind wallboard. They insisted it would not fit, but I found out later when I had another HVAC company install the same units at my work office and did place lines behind wall board behind 2x4's. Be honest will ya! 2) Installer damaged a valve in condenser causing unit to leak which needed replaced. I asked for a new condenser, but Climatech refused and repaired. and warranted the repair. I would have rather had new. 3) Installer split the copper line in two places. A 2nd installer had to come out several days after install to repair and finish install. I requested a new copper line, but they again refused, but instead warranted the repairs. I again wanted new. 4) They sale the unit as most quiet in industry, but when it get's below 40 degrees outside condenser hums and struggles over condensation. The inside unit gurgles and whistles and hisses over it as well. They had a Mitsubishi person come out. Their response is unit runs normal and the operations manual states that the noise is because of condensation and won't do anything further about it. I would have not ordered the unit knowing this. They should list this before selling it. Emailing me an operations manual after the fact of install and payment is just not an acceptable response. Neither Climatech nor Mitsubishi is showing any integrity nor addressing the noise problem. I would not use either again. I am exploring legal options and trying to develop a class action legal case over false advertisement to obtain a replacement unit to eliminate the noise or refund. Very disappointing to spend the one and get this from companies such as this. Email me for more information [email protected] Look at the pictures to see how bad their install looks in a finished room over the false position of their installer."

FAQs for mold testing and remediation projects in Pittsburgh, PA

Some states require mold removal specialists to be licensed, while others require licensed mold testing companies to create remediation protocols that any contractor can carry out. You can use our state licensing tool to find requirements in your area. In either case, it’s imperative that you hire an experienced professional for mold removal to ensure the safety of your home and your family.

It’s possible to scrub mold off of visible surfaces yourself, but it’s not usually a good idea. Mold is not only a potential health risk, but it’s also difficult to treat in its entirety, especially because it can grow behind walls and in other hidden areas a DIYer might miss. Since mold is a serious and often pervasive issue, you should hire a professional that will remove all of the mold—including any that might be hidden—run industrial air scrubbers to remove airborne particles, and complete mold testing to ensure the underlying problem is solved.

The most effective way to remove mold includes testing affected surfaces and the air for spores, creating a protocol for removal, carrying out the steps within the protocol, running air scrubbers for the recommended amount of time, and then completing a post-remediation round of testing to confirm the issue is solved. Since this work is very involved and there are health risks if done incorrectly, you should always hire an experienced professional to handle mold removal.

The average cost for mold remediation is around $2,200, and most projects fall somewhere between $1,100 and $3,300. Your total will depend on many factors, including the surface area that is affected by mold, the extent of the issue, how much building material your professional needs to replace, whether or not testing is necessary for safety reasons, and existing indoor air quality.

Mold removal will take between one and five days in most cases, but severe mold issues can take several weeks to correct. Your timeline will depend on how much mold there is in your home, where the mold is located, and how much testing and aftercare is required. If you have mold behind your walls or you have an excessive amount of mold that requires removal and running air scrubbers for several days, you could be looking at over a week for the process to be completed.
