"The work was completed in a timely manner. The gutters were rehung using extra hangers every 12 inches instead of the original 24 inches. There was a strong downpour the day after the work was completed and the rainwater flowed in the downspouts correctly."

"CW shows up on time. He does everything very quickly but detailed at the same time. If you have a list of "honey do list", stop fighting with your spouse regarding who should do what, and just have CW do them for you. I count myself pretty handy, but what would take me an hour would only take him 20 minutes to do. I have started writing down a list of things needed to be done around the house, and then will just call him up when we have a good amount.

Crew showed up on time each day and went right to work.  Cleaned up each day before they left.  They were great to work with and delivered what they promised.  This was a small job but they treated it as if it were the only job they had.


It is to my shame that I took so long to write this review.  I've ben too busy enjoying the patio (maybe not so much during current season).

Nikki arrived right on time and was very polite and courteous. She provided all of her own cleaning supplies including vacuum cleaner and she asked questions to better understand what it was that we were needing from her services. In a little less than 3 hours, she had performed a thorough cleaning of our entire home, including all 3 floors (upstairs, TV room downstairs and the main level). Her attention to detail is exquisite! Our kitchen sink is still shining to this day! We accidently left our toaster on the counter and I think it had honestly been cleaned once the entire time we've had it, but to our surprise Nikki had it looking brand new. We did not expect her to clean our toaster at all, so we were just shocked to see it like that when we came into the kitchen. She wiped all of our baseboards and vacuumed every step (just some of my favorite details of which she went above and beyond), not to mention cleaning between the oven glass and even the laundry room! It was wonderful! 

Originally, we were only looking for a one time clean before the holidays but Nikki did such an extraordinary job that we have hired her full time for a bi-weekly, full-service clean of our home. She is that good and we highly recommend her services!

Glass Block questions, answered by experts

Their thickness depends on application, but most glass walls are typically 3/8 to 3/4 of an inch thick. Although it’s not as common, single panes of glass can also be 1 inch thick.

Glass block installation can be relatively expensive due to the range of material costs and the labor time to assemble this type of specialty window. The process proceeds slowly as the glass does not absorb moisture from mortar and silicone caulk takes longer to harden, leaving spacers to hold up the structure until the caulk or mortar begins to cure. Plus, if your current windows have structural issues or damage, you’ll need to repair them before beginning the project, increasing your bottom line. 

Most installations take 1-3 days, depending on the number of blocks and customization requirements.

Heavy glass tends to be more expensive than thin glass because it is stronger and more durable. In most cases, ¼-inch-thick glass is ideal for mirrors, and ⅛-inch-thick glass is ideal for residential windows. Heavier glass isn’t always necessary, and can be more challenging to hang or install. Work with a local window installation pro for replacement or new construction windows.

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.
