When I bought my circa 1984 Reston town home 6 years ago, I didn't realize how many things were not "standard" size. When the Fairfax County Fire Department forced entry through my front door (due to a small fire next door) which caused me to replace both the door and the jamb, not even *that* door could be installed without serious tweaking and modification by professional door installers. Therefore, it came as no surprise that when something as "simple" as a sliding screen door on my deck, which was the wrong size to begin with, finally gave up the ghost entirely, the search to find a properly fitting and functioning screen door became a quest. Nothing HD and Lowes sold would fit. Nor were their employees vaguely knowledgeable. I found an on-line company that custom makes screen doors/windows to specification, but measurements had to be to taken (by me) to the closest 16th of an inch. Their on-line instructions were rather intimidating and the diagrams caused more consternation than confidence. Although I am capable of many home fixes, I was concerned that I would spend over $200 only to wind up with a non-returnable 32"x80" paper weight. My living room is small and most of the rear wall is comprised of French doors that look out across my deck and trees. I've always considered it a living painting and often thought a retractable screen would be most aesthetically pleasing, allowing the view to be uncluttered by screening, which currently was seen through one side of the door or the other, regardless of its position. Not to mention I had a high degree of concern that the door be absolutely bug-tight! I love to let the air in, but not bugs, which seem to have an affinity for both my deck and my person. If the screen door could not fit tightly enough to keep out the smallest of intruders, then I might as well seal the doors and treat them as windows. I called no less than 5 contractors/general handymen from Angie's List hoping to find someone who would take measurements, install and, if necessary, tweak a new sliding screen door. No one would touch the job. Too much trouble for too little money, they said. I found Tri-State by trolling the web. They had a "cicada special" in May. I called. Phone staff was friendly, informative, answered all my questions and allayed most of my concerns. It was more money than I had been willing to spend when I began my search two years ago, but after ending up at so many dead ends the cost was softened when I factored in their warranty, that they come and custom fit the door on your property and they will come out and address any problems for two years. I told Tri-State I had to have my siding painted before I was ready for the screen door, so the installation was finally done in June. I was told they would come between 8:00 and 9:00a during the week. They came at 8:15 and I was on the road to work in a hour. Carl and a helper measured my doorway, set up a saw horse and custom fit the door on the front sidewalk after plugging in their saw in my kitchen (no outlet at the front of my house). They installed the door jamb on top of the existing aluminum threshold. Carl showed me how to re-seat the screen in case some person/dog walks through it. Also, how to keep the tracks clean and lubricated with silicone spray (NOT WD-40). They left me a can of lubricant when they were done. The whole process was quick and painless and I wish I had bitten the bullet a few years ago. I'm very happy that I have an unimpeded view of my deck and trees 24-7 and I am looking forward to having my door open to the air while keeping the bugs out once the humid summer changes to autumn.
