I am a self employed General Contractor with subs who work under me, but also with me. I work on every job and I handle all my affairs. I always work under contract and with estimates. By the hour is exactly that, by the hour! I specialize in all phases of construction. I have been in construction for over 30 years and I am fully insured and registered with the State of NH. I am lead certified and I have a mold remediation company that does all my mold work. I do not charge for travel, as that is something you have to do to get to work. I work every job differently on the billing procedures, as not every job is the same. I work with customers on all phases such as design, paint schemes, window layout, lighting, doors, and general footprints for small additions and garages. I do all my own dirt work straight through to the finish work. And most importantly, when you call my phone, I answer it, day or night!

FAQs for glass block service projects in Londonderry, NH

Typically, glass block windows last about 15 to 30 years, slightly less than regular windows, which last 20 to 50 years. Resealing glass blocks can help extend the lifespan of this bathroom feature. The key to ensuring that glass block windows last as long as possible is to have a professional glass block installer place them. Glass block pros will have the skills, tools, and knowledge required to install these special features into any space, noting obstacles like damaged windows or too-cramped areas during the consultation.

Installing glass block windows has benefits and disadvantages, as with most materials. The pros and cons can vary depending on the type of glass block and the window location.

Pros

  • Maintains privacy while letting light into the bathroom

  • Energy efficient

  • Sealed to prevent drafts

  • Aesthetically pleasing

  • Strong and secure

Cons

  • Costly to install

  • Challenging installation

  • Challenging repair

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. 

The average cost to install glass block windows is about $710, ranging from $460 to $1,000, depending on the size and design of the window, installation type, and location. Different styles of glass blocks also impact the cost:

  • Clear glass blocks: $10–$30 per block

  • Colored glass blocks: $25–$40 per block

  • Acrylic glass blocks: $15–$25 per block

  • Wavy glass blocks: $10–$30 per block

  • Alpha glass blocks: $15–$25 per block

  • Ice glass blocks: $20–$35 per block

  • Diamond glass blocks: $20–$75 per block

  • Frosted glass blocks: $30–$35 per block

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.
