How we quote for glazing silicone
Jobs vary more than people expect. The main factors:
- When we can work, for business premises
- Any mould that needs treating
- The amount of work
- Whether the work is at height
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Any previous sealing or DIY work
- The address or postcode of the job
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved before giving you a price.
About our glazing silicone in Letcombe Regis
Glazing silicone that has yellowed, blackened or come away spoils the look and lets water in. It comes off cleanly, without marking the glass before the new bead goes in. If you have rooflight joints letting water in and leaks where conservatory glass meets the frame, we can help, on shower screens, glass-to-glass joints and glass balustrade bases alike.
Mastic can only go onto a dry, clean joint, so window work in Letcombe Regis is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Big or small, you get the same one-year guarantee.

Common problems we fix in Letcombe Regis
Heat and cold make glass and frames move, and they do not move by the same amount. Over years, that movement tears the silicone.
Signs it’s time to call us include:
- Shower screens leaking along the wall or tray
- Split or lifting silicone on glass
- Cracked silicone between glass panels
- Failed sealant around rooflight glass
In the older streets around Church of St Andrew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Frames and glazing around Letcombe Regis
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as St Nicholas CofE Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What the job involves on each surface
Shower screens
Black or peeling silicone on a screen lets water out. Cutting it out and resealing fixes it.
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
Should I try it myself first?
If you are set on DIY, put the effort into 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 call for the right materials, safe access and experience.
How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. Somewhere like Letcombe Regis needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by finding the leak and making sure sealant is the cause.
- 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.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Tell us about any water getting in

Common questions in Letcombe Regis
Is Letcombe Regis within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is glazing silicone in Letcombe Regis guaranteed?
All our work, in Letcombe Regis and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you replace glass?
That is not something we do. A misted unit has failed inside and needs replacing by a glazier.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
What sealant do you use on glazing?
A neutral-cure glazing silicone that suits the glass and frame. In bathrooms, we use anti-fungal silicone.
Where do you work from?
Mr Mastic is based in Crawley. We cover Letcombe Regis and the rest of Oxfordshire.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Get a new leak looked at quickly
- Use a gentle glass cleaner and a soft cloth
- Ventilate the conservatory to cut condensation
- Do not use a blade near the sealant
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
Cracked glazing silicone means the joint has failed. Resealing now is a small job, compared with repairing damaged frames or plaster.
