FAQs for Mattingley
Can you do window mastic in Mattingley?
Yes, Mattingley is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Is Mattingley within the area you cover?
Yes. Mattingley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can resealing stop a draught around my window?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.
Does the work come with a guarantee?
Yes, with our one-year guarantee. Keeping drainage clear and checking the joints yearly helps them last.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
Window mastic for homes and businesses in Mattingley
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. Typical jobs include rain getting in at the frame or under the sill and white mastic on grey or black frames, across timber windows & doors, uPVC windows and window sills.
Homes in small places like Mattingley often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Clear any debris from frame drain holes
- Paint up to the joint, not over it
- Wash the frames with mild soapy water
- Keep paint and stain on wooden frames in good order
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.

What else we do in Mattingley
When to call us in Mattingley
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
People normally contact us when they notice something like this:
- Water coming in at the bottom corners of a door
- Gaps left after new windows were fitted
- White mastic on grey or black frames
- Hard, cracked sealant around windows
Homes close to Mattingley Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Before booking anyone

- Which colour the sealant will be
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
What happens on the day
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a morning for a couple of windows and a door for a typical job. In a small place like Mattingley, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children

Advice
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- A door that needs adjusting, rehanging or new seals
- A sash or casement that will not close properly
- Damp problems in the wall away from the window
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

What window mastic looks like in Mattingley
With historic houses such as Stratfield Saye House (about 3.1 miles north-west) nearby, there’s older building stock in the area around Mattingley as well as newer homes. In older buildings, 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Hook station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
