Window mastic in Polegate, done properly
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on composite doors, aluminium frames and window sills, and people most often call us about water coming in at the bottom corners of a door and cracked internal joints between frame and plaster.
In smaller places like Polegate, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Surface by surface
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Clear any debris from frame drain holes
- Avoid harsh chemicals near the mastic
- Use gentle cleaners on frames and sealant
- Walk round the house once a year and look at the joints
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Common problems we fix in Polegate
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. Backing rod sets the right depth.
It’s worth asking for a quote if you see:
- Hard, cracked sealant around windows
- Cold air getting in at the frame edge
- Leaking joints at the ends of sills
- Sealant in the wrong colour for the frame
Managing a site like Polegate Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Questions from Polegate
I let a flat near Polegate station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you cover Polegate for window mastic?
Yes, Polegate is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear quote.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Can new window sealant be painted?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Tell us if you’re decorating and we’ll choose accordingly.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Are you insured?
Yes. Mr Mastic is fully insured.
Can resealing stop a draught around my window?
In many cases. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Quotes for window mastic in Polegate
The price is agreed before any work begins. It takes into account:
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- The type of sealant required
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Pictures of the joints, sent by email
- How we’d reach the joints
- Roughly how big the job is
- If someone has resealed it before

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, the area is protected and the work begins. Most jobs take most of a day for a typical house, less for a few frames. Parking around Polegate is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

Advice
Windows and doors in Polegate
Historic houses like Michelham Priory (about 3.2 miles north-west) are a reminder that the area around Polegate has older buildings as well as new. 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.
If you let a flat or house near Polegate station, renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near St John's Church of England Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Landmarks near Polegate

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Why it’s worth doing now in Polegate
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In a smaller place like Polegate, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
