How we handle window mastic in Warborne
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. If you are dealing with gaps where the sill meets the wall and mastic that has split away from the wall, we can help, on patio & French doors, window sills and composite doors alike.
Somewhere as small as Warborne, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

What we are called out for in Warborne
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
If you can see any of these, it’s time to have the joints looked at:
- Cracked internal joints between frame and plaster
- Cracked sealant at the sill ends
- Old mastic that has gone black or come away
- Cracked or shrunken mastic around the frame
Managing a site like Southlands School? Then the mastic around its windows and doors needs looking after like any other building’s.

What else we do in Warborne
How it works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for a few frames, or a day or more for a whole house. Somewhere as small as Warborne, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Let us know about parking restrictions

Advice
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Repaint timber before it’s bare
- Avoid harsh chemicals near the mastic
- Ventilate rooms so frames don’t stay wet inside
- Make sure the drainage slots aren’t blocked
Try not to touch the new joint while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
How we quote for window mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- The number and length of the joints
- Any working-time requirements on site
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Any previous sealing or DIY work
- What’s wrong with the joints now
- Where the job is, and your postcode
- Whether it’s a home or a business
To get a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We’ll give you a clear quote before any work starts.
Warborne homes and the weather
Warborne is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Lymington Town station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Homes close to Saint Nicholas Chapel include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions from Warborne
Does the coastal weather in Warborne affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Lymington Town station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
How much does window mastic cost in Warborne?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or send us an email with a short description of the job.
Are you insured?
Yes. Full insurance covers our work.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. We will tell you how long your job needs when we quote.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
What the job involves on each surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
