Glazing & conservatory sealant in Headley, West Berkshire
Problem with your glazing joints in Headley? We remove the old material, prepare the joints and seal them properly.
- Silicone pulling away from the glass
- Water running down inside the glass
- A quick top-up bead that didn’t last
Common problems we fix in Headley
The wrong sealant is a common cause. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.
Look out for any of the following:
- Glass-to-glass joints that have split
- Rooflight joints letting water in
- Silicone pulling away from the glass
- Stained, discoloured glazing silicone
For landlords with property near Thatcham station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Glazing silicone in Headley
Glazing silicone is a maintenance item. Weather and movement take their toll and cracked joints let water in. Resealing puts that right. Typical jobs include glass-to-glass joints that have split and conservatory leaks at frame and glazing joints, across glass-to-frame joints, glass-to-glass joints and rooflights.
Outdoor sealant needs dry, clean surfaces, so work on frames around Headley is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, you get the same one-year guarantee in Headley and across West Berkshire.

Headley homes and the weather
Historic houses like Shaw House (about 4.4 miles north-west) are a reminder that the area around Headley has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Cheam School? Then larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Peter, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on how many joints need doing. For a village or hamlet like Headley, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Keep air moving in the conservatory
- Stick to mild cleaners on glass
- Don’t leave a drip for the next storm
- Avoid scraping close to the bead
Do not use blades or scrapers near the bead when you clean. A soft cloth or sponge is best.
Cracked glazing silicone means the joint has failed. Resealing now is a small job compared with fixing water damage later.
