No other home inspection company in Maryland requires such intensive inspector training program. In other words you can be assured your inspector will protect you and your family. We back all our inspections with a 200% Guarantee and a 90 day Guaranty.
"I used 4u inspection to inspected a 2017 single family house. I had an inspection done virtually due to COVID which understandable but I was really disappointed with the service. The inspection was scheduled at 9:00, I was surprised inspection was done at 10:30 so basically an hour and half for a single-family inspection. I was moving some items to our house and in my first couple hours I see the inspector missed an obvious problem with the refrigerator, every time you open and close the fridge it makes a loud knocking noise, the noise is so obvious that I think he did not even open the fridge, 4 window shades had a damage cord, a window was not opening properly. I spoke to them on the phone before I post any reviews and the inspector manager was polite but claimed that the inspector is not suppose to check shades or windows and that they only need to check the refrigerator water connection and if it cold and it is not their responsibility to check if there is noise coming from the fridge ? . The roof was inspected the old way with binocular which has limited vision. Advanced inspections companies use drone to do this. I thought I would give an honest review for others to know what you might get from their service. I think I would have saved my self the inspection money and couple thousand dollars if I have done the inspection myself as all the issue found by the inspector were really minor but missing a major issue."

Americlean Services Corp
Americlean Services Corp
Americlean Services Corporation is the Washington DC metro area go-to provider of Indoor Air Quality (IAQ) services. We provide a wide variety of IAQ services to commercial, government and residential customers in Northern Virginia, DC and the surrounding communities. From air duct cleaning to water damage restoration, we have the experience, tools and know-how to get the job done right. We’ve been serving the D.C. area since 1984. We were founded in Vienna, Virginia by Dr. Karl de Azagra and later moved to Manassas Park, VA to accommodate the expansion of the business.
"Setting up the service was an efficient process with the representative listening to what we needed done and providing a (reasonable) price over the phone. On the day of our service, the two-man crew was punctual, friendly and efficient. We initially walked through the house identifying all the registers and discussing the process. They then went to work and continued diligently and efficiently for over four hours. We were impressed with their attention to detail and care for our house (covering their shoes with "botties" when coming in from the wet outside; laying down when they started, a drop cloth by our front door where they stationed their heavy-duty HEPA vacuum; and then going around after they finished to vacuum bits of dust and paint that had fallen on our floors near registers that had been detached). Excellent experience."
