SLIDING SASH WINDOW REPAIR
The lower sash spring had failed, preventing the window from opening. As the upper sash was out of reach and never used, I transferred its spring to the lower sash.

The lower sash is now fully operational, restoring ventilation with no replacement parts required and saving the client both material and labour costs.

DO NOT LEAVE YOUR BLOWN UNITS!
The mechanism can corrode from the inside out, turning a small issue into a costly repair.

Take a look at this recent job and see how I fixed it. I even managed to reuse the exiting handle, saving the customer a bit of money while getting everything working properly again.

DO YOU HAVE A WINDOW STUCK SHUT?
When the handle was released and turned, nothing happened. I removed the handle and found the gearbox mechanism had worn into a round shape (should be square), indicating the gearbox needs replacing.

To avoid damaging the window I carefully removed the glass unit, opened the window and replaced the gearbox.

INCORRECTLY FITTED FIRE DOOR CLOSERS REPAIRED
8 Fire doors had door closers fitted incorrectly. The client advised they were told by the carpenter that, "they will work if the windows were open"!

See below how I professionally corrected the installation to ensure the doors close safely and operate as intended.

ANOTHER BI-FOLD DOOR PROBLEM DUE TO POOR INSTALLATION!
The bi-fold door bottom was rubbing on the bolts. At first, the door didn’t appear to have dropped, but the silicone at the top of the frame was actually holding it in place where the frame had sunk due to poor installation.

The frame was also moving because the silicone was taking the weight, as no proper fixings had been added apart from at each end.

Watch the video below to see how I fixed the issue.

I TAKE ON SMALL CARPENTRY JOBS TOO!
Bit of a different one today. I'm primarily a locksmith, window and door repair specialist, but I also take on small carpentry jobs,( up to a days work). If you've got those smaller tasks that are hard to get a carpenter for, I'm happy to help.

This client wanted the decking reduced to provide more room on their terrace.

FIRE ESCAPE HINGES INSTALLED FOR SAFETY
While working on a clients window, I noticed there were no fire escape hinges installed.
I recommended adding them, as its important for safety, at least one window in every bedroom should be fitted with fire escape hinges.

See the video below showing the before and the picture shows the after.
