How we handle window mastic in Bartley
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. If you have a bead that doesn’t match the frame and old mastic that has gone black or come away, we can put it right.
Around Bartley, 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.
We stand behind the work with a one-year guarantee.

Common questions in Bartley
Do you cover smaller places like Bartley?
Yes, Bartley is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Ashurst New Forest station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you do the inside joint as well?
Yes. Inside, the joint between frame and plaster is sealed neatly.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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 doesn’t work out, we can still put it right.
Why it’s worth doing now in Bartley
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Older cottages and farmhouses around Bartley can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.
What you get with us
- A 12-month guarantee on all work
- Old sealant always removed completely
- We leave the area clean and tidy

What we are called out for in Bartley
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
People generally contact us when they notice something like this:
- Whistling draughts around closed windows
- Gaps left after new windows were fitted
- Mastic that has split away from the wall
- Gaps between the frame and the inside reveal
Managing a site like Bartley Church of England Junior School? Then the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- Is VAT in the price?
- What happens if they find a problem under the old sealant
- What insurance they hold
- Who turns up on the day
What affects the quote in Bartley
Jobs vary more than people expect. The main factors:
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- Working hours on commercial sites
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- The problem you’ve noticed
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- Where the job is, and your postcode
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.
What we do, step by step
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes most of a day for a typical house, less for a few frames for a typical job. Somewhere like Bartley needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in

Advice
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Wipe condensation off the frames
- Don’t use solvent cleaners on the joint
- Keep paint off silicone joints
- Make sure the drainage slots are not blocked
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Wet, windy weather is when failed mastic shows itself, 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 window mastic looks like in Bartley
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Ashurst New Forest station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
