Surface by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Window mastic for homes and businesses in Christmas Pie
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. Common call-outs are for mastic that’s falling out in pieces and untidy mastic left by window fitters, across window sills, aluminium frames and uPVC windows.
Homes in small places like Christmas Pie 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.
Whatever the size of the job, it’s backed by our 12-month guarantee in Christmas Pie and across Surrey.

What else we do in Christmas Pie
Leave it or put it right?
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Older cottages and farmhouses around Christmas Pie can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
Why choose Mr Mastic in Christmas Pie
- 20+ years of sealant experience
- Colour agreed with you before work begins
- We never seal over old sealant
- Fully insured
Aftercare tips
Good habits help new joints last longer. Our tips:
- Air rooms to keep condensation down around windows
- Make sure the drainage slots are not blocked
- Avoid blasting the frames with a pressure washer
- Check the mastic once a year
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
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. If you notice one, it’s time to get the joint looked at.
Christmas Pie: your questions answered
Can you do window mastic in Christmas Pie?
Yes, Christmas Pie is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
I let a flat near Wanborough station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can resealing stop a draught around my window?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Can you reach windows above the ground floor?
Yes, where they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
How do I get a quote for window mastic in Christmas Pie?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.

When it isn’t the sealant
New sealant cannot fix everything, and we will tell you before any work starts. It will not solve:
- Damp problems in the wall away from the window
- Broken hinges, locks or handles
- Rotten timber, which needs a joiner first
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

How we quote for window mastic
Jobs vary more than people expect. The main factors:
- The size of the job
- How many areas need sealing
- When we can work, for business premises
- Access and height
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What we need to know
When you contact us, these details help:
- The type of property
- Where the property is
- Photos by email, if that is easy
- Any previous sealing or DIY work
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Do you need window mastic in Christmas Pie?
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That is what backing rod is for.
The problems people normally mention when they call include:
- Damp patches on the reveal after heavy rain
- White mastic on grey or black frames
- Old mastic that has gone black or come away
- Gaps left after new windows were fitted
If you live in an older home near Church of St Bartholomew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

We bring what the job needs, so it can be finished in one trip where possible.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.

- We clear up and check every joint is fully closed.

Advice
Window mastic in Christmas Pie: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Wanborough Manor (about 0.6 miles south-east) are a reminder that the area around Christmas Pie 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.
Rented homes near Wanborough station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Puttenham CofE Infant School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
