"This is our second door purchased from Secure All, different house. Both experiences were FANTASTIC! The quality of the product and the incredible high level of customer service is outstanding. Very professional from start to end. The price of the doors are higher than others, BUT, go and compare and you will see the difference. What you will not be able to compare is the awesome customer service and the dedication they have to ensure your door is what you wanted and properly installed. Truly a great company offering an incredible product that takes great pride in what they do! THANK YOU AGAIN!!!!!!!!!!!!!!!"

"The entire process went smoothly. The reservation went quickly, once we paid an extra $200 to reduce the pickup window to 3 days. The pickup and drop off process also went well. The car was returned in the same condition we left it. We would recommend using United Freight."

"Excellent. Got our bid from Brian to replace the electrical panel (as ours was a serious safety issue) and do several fixes, small installs of electric throughout house. The bid was spot on and very fair in price (I had done my homework). His crew arrived on time, worked quickly and efficiently, cleaned up after themselves and stayed after normal business hours to get the lengthy task of upgrading the panel done. When the inspector reviewed the work, said it was on par with top notch commercial install and to the standards he would do in his own home. I'll be using Brian again (hopefully) soon when I complete our remodel."

"Don is really great.  We had a time crunch because new kitchen cabinets were about to be installed when we realized we didn't have the right venting in place.  He responded immediately, did the work promptly when others refused to take on the work with the unfortunate short notice we were forced to offer, found a much better way to run the vent than we had in mind and did the work to perfection.   He has a vast array of construction skills beyond the ones he lists so he may be able to help in ways you didn't even think possible.  His prices are very fair.  We strongly recommend him and will be calling him again, for sure when the need arises. <br /> <br />"

"2 new sliding glass doors installed. Work was done quickly and with high quality. Great attention to detail, full cleanup and haul away, competitive pricing. Would definitely recommend!"
