"We were convinced to have our roof done after the roofing expert inspected our roof and sat us down for his presentation. We appreciated the time spent to explain the project management plan from the delivery of materials to the post-installation inspection. Everyone we met was very professional and the clean up crew did a great job."

"I live in Las Vegas, NV and my Mother lives in Baltimore City. Last month my Mother called me to inform me that she had water build up on her porch roof. I reached out to home advisor and found Weather Seal Home Services. I m really grateful that there are still GREAT People running GREAT Companies! Michelle and Dean made this entire experience pleasant and hassle free. From the beginning when I reached out to the final inspection of the work, they are what we call Professional! I just have two words for Weather Seal Home Service... THANK YOU!!!"

"We've hired JW for everything from painting to plumbing, carpentry, pressure washing, outdoor and indoor work. The approach where you pay by the hour for all manner of tasks instead of parceling them out to different service companies has worked so well for us! They send the best person for your particular job. And they are consultants too...they will give you ideas on how to correctly complete projects, as well as save money when you can. We like how responsive the office is, how the owner is still involved with the day-to-day, and the quality standard that each technician applies to his or her work. And if anything comes up (as it does with home repairs and life), JW will work with you on it. We've worked with 5 different technicians and 2 different estimators for four different days of work at two different homes. Highly recommended!"
