About our window mastic in Rowledge
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We are often asked to deal with rushed sealant from a window installation and a bead that doesn’t match the frame, on composite doors, patio & French doors and timber windows & doors.
Around Rowledge, 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, phone 0345 464 0079 or email us.

What affects the cost of window mastic
For a quick quote, just ask. What matters most is:
- Mould in or behind the old joints
- The old material and how stubborn it is
- Any working-time requirements on site
- How easy the joints are to reach
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Landlord and commercial work in Rowledge
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We also work for property managers and facilities teams in Rowledge and across Surrey. We can quote a run of properties together, and we are fully insured for the work.
What happens if it’s left?
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In a small place like Rowledge, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Common questions in Rowledge
Is Rowledge in your area for window mastic?
Yes. We work across London and the South East, and Rowledge is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Do you cover smaller places like Rowledge?
Yes. Rowledge is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I try DIY first?
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.
Can you do the inside joint as well?
Yes. Indoors, we seal between the frame and the plaster or reveal.
Does the work come with a guarantee?
Yes, for 12 months. A yearly look at the joints helps them last.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Frames and glazing around Rowledge
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Farnham Castle (about 2.6 miles north) nearby, there’s older building stock in the area around Rowledge 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.
Letting a property close to Bentley (Hampshire) station? Then renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Rowledge Church of England Controlled Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What’s near Rowledge

Rowledge’s nearest station is Bentley (Hampshire) station, roughly 2 miles west of the centre.

What we are called out for in Rowledge
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That’s what backing rod is for.
The most common problems we see are:
- Leaking joints at the ends of sills
- White mastic on grey or black frames
- Draughty joints inside around the window
- Cold air getting in at the frame edge
In the older streets around Saint James, the joint between an old wall and a newer frame is normally the first place rain gets in.

What else we do in Rowledge
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Clean frames with a soft cloth and soapy water
- Look round the frames every year or so
- Don’t paint over the silicone
- Keep paint and stain on wooden frames in good order
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
The process
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from an hour or two to a full day, depending on how many frames there are in most cases. Somewhere like Rowledge 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 look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we are working on
- On commercial sites, let us know about site rules
