What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of frames, longer for a whole house and we leave things clean and tidy. Somewhere like Roundbush Green needs a little journey planning: 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.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Clear items away from the joints we are working on
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit

How we handle window mastic in Roundbush Green
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. Where the air is getting in through the window itself, we will say so. If you are dealing with cracked or shrunken mastic around the frame and draughty joints inside around the window, we can put it right, whatever the surface.
Around Roundbush Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

Roundbush Green: your questions answered
Is window mastic in Roundbush Green guaranteed?
All our work, in Roundbush Green and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Is Roundbush Green in your area for window mastic?
Yes. Our work covers London and the South East, and Roundbush Green is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can you get sealant to suit coloured frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Can you do upstairs windows?
Usually, yes. We plan safe access before the job, so mention the height and anything in the way.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Can I paint over the new sealant?
Silicone generally won’t take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Can resealing stop a draught around my window?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we’ll say so.
What we can’t put right
A few problems are outside what sealant work can do:
- Worn gaskets, brush seals or a door that has dropped
- A failed sealed unit that has misted up
- Soft or decayed wood in the frame
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.
Where we work in Roundbush Green
- Composite doors
- Aluminium frames
- Patio & French doors
- Window sills
- uPVC windows
- Timber windows & doors
What the job involves on each surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Why deal with it now?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Where a wall is exposed, as many are in small places like Roundbush Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Windows and doors in Roundbush Green
With historic houses such as Barrington Hall (about 3.1 miles north-west) nearby, there’s older building stock in the area around Roundbush Green as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Rodings Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. Homes close to Parish Church of St Mary include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
