"I gave this man $3000 which was 33% of the job upfront. Was supposed to give him 33% at the halfway part And 34% upon completion. But when I went to my bathroom and realized you left drugs in my bathroom and I have small children. Not like that 3000 black and small cleaners caught easy and heâ s lucky he hasnâ t been charged with nothing. Only reason that happened is because I wouldnâ t pursue charges. He obviously is a drug addict and has a problem so maybe he should get help Possibly isnâ t the option maybe rehab is. If you paid for supplies, you got ripped off wait 10 years and it will all fall apart charges for certain stuff but buys different stuff so he can use the extra money to pick himself up drugs without nobody noticing, I am so terribly in grief over this. $3000 he ran off with how is Matt doing in business and not in a jail cell"

Doors (exterior) installations and replacements FAQs

Replacing a patio door usually takes between three and five hours. This includes removing your old door, fixing any damaged areas, and precisely installing and sealing the new one. If your door has a complex design or larger dimensions, it might take longer, since additional adjustments are needed to ensure everything fits perfectly.

Even if your patio door doesn't look broken, it might still be inefficient or insecure. Signs it's time for a replacement include squeaking or scraping noises when you open or close the door, cracked frames, condensation on the glass or frame, gaps between the door and frame, or feeling a draft when you're nearby.

If the glass in your patio door breaks but the door itself is still in good shape, you can just replace the damaged pane to get it working again. This involves removing the broken glass, carefully installing new high-quality glass, and making sure everything is sealed properly for energy efficiency. This repair brings back your door's appearance and function without the cost of a full replacement.

Sliding glass doors offer abundant natural light and create spacious interiors, yet they provide less security and reduced insulation compared to wood or metal options. Upgrading the glass to a multi-glazed option enhances both insulation and security, optimizing energy efficiency and durability. This premium upgrade offers substantial improvements in overall performance and resilience.

A patio door lasts 20 to 30 years when installed with precision and maintained consistently. Proper installation, regular cleaning, and prompt repairs extend its durability, while robust construction ensures enhanced energy efficiency and security. Consistent maintenance increases service life and preserves beauty, adding long-term value and functionality to your home.
