Glazing silicone for homes and businesses in Mackerye End
Across Mackerye End, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method, with a sealant chosen for the joint. We are often asked to deal with leaks from the base of a shower screen and a quick top-up bead that didn’t last, on shower screens, glass-to-glass joints and glass-to-frame joints.
Mastic can only go onto a dry, clean joint, so window work in Mackerye End is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- A frame that needs repairing or replacing
- Leaks from the roof covering or flashing (a roofer’s job)
- A sealed unit that has misted inside
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Joints and surfaces we work on
- Conservatory frames
- Glass-to-glass joints
- Rooflights
- Glass-to-frame joints
- Shower screens
- Glass balustrade bases
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
Windows and doors in Mackerye End
Historic houses like Shaw's Corner (about 2.3 miles east) are a reminder that the area around Mackerye End has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Harpenden station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows. In the older streets around All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How we quote for glazing silicone
For a quick quote, just ask. The main things that affect it are:
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- How many areas need sealing
- Access and height
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
What to tell us for a quote
When you contact us, these details help:
- The problem you’ve noticed
- The type of property
- Any previous sealing or DIY work
- Where the property is
Want a quote for glazing silicone? Please phone 0345 464 0079 or email us with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What happens if it’s left?
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before you notice. Older cottages and farmhouses around Mackerye End can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most jobs, and the area is left clean. In a small place like Mackerye End, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We look over every joint and, where we can, test it with water.
Preparing for the visit
