"Mike was very knowledgeable and courteous about the entire install from laying drop clothes when he worked inside to vacuuming inside and cleaning up anything that was left behind from the old windows and materials from the install of the new windows as well and my husband and I were very impressed with the way the new windows look and how well they work. Karen the salesperson was very knowledgeable and explained what no other company did about how windows are usually made and how they work and what makes windows from Universal so much better than the competition at a reasonable price that added value to our homes equity as well as vastly improving how our home looks inside and out."

My name is Kristen. I currently have around 6 years of cleaning experience, but have been cleaning on the side since I was 19. I have three children and am married. I am willing to negotiate price, what is to be cleaned, when and what time. Please feel free to ask me! Have a great day!

"The installation was efficient and satisfactory; however, I would have appreciated it if the sales rep, when meeting with me at my home and going over the options, would have pointed out that the color of the window frame would not match the color of surrounding wood."

"We are very pleased. We interviewed a number of security companies and received proposals including DIY to the big national and regional companies. I was not satisfied with any of the companies until I learned of 1stSecurity. Their pricing was good, both for the monthly fee ($40) and for the cost of the equipment. The manager, Jeremy, was very open and straightforward. The installer was also excellent. We asked them to install system prior to a trip we were taking in a few days and they met this short timeframe. The installation took 1-2 hours. The equipment we purchased was fairly extensive as we have a fairly large house and we wanted comprehensive coverage. This included 2 glass break sensors, a motion detector, and numerous door and window switches as well as a fire detection monitor. I accidentally set off the alarm and received a call from the monitoring company in under 10 seconds. The control panel for the system is an easy to use touch screen device, similar to an iPad. The system is very capable so you can connect smart devices to it if so inclined. We have been very pleased with the product and service so far (about 2 months)."
