Window & door mastic in Cuddington, Buckinghamshire
Window and door frames in Cuddington need attention? We remove the old material, prepare the joints and seal them properly.
- Rain getting in at the frame or under the sill
- Cracked or shrunken mastic around the frame
- Cracked sealant at the sill ends
How we handle window mastic in Cuddington
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. If you have water coming in at the bottom corners of a door and whistling draughts around closed windows, we can put it right, on aluminium frames, uPVC windows and patio & French doors alike.
In a village or hamlet like Cuddington, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
You get a 12-month guarantee, the same in Cuddington as everywhere else we work.

When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Worn gaskets, brush seals or a door that has dropped
- A sash or casement that will not close properly
- Damp problems in the wall away from the window
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.

Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Landlords, agents and businesses in Cuddington
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
How the job changes by surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Cuddington: your questions answered
Do you work for landlords with property near Haddenham & Thame Parkway station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Is Cuddington within the area you cover?
Yes. Cuddington 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.
Will new mastic stop draughts?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
How do I get a quote for window mastic in Cuddington?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Leave it or put it right?
Resealing frames is a short job: the visit takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Where a wall is exposed, as many are in small places like Cuddington, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

The process

- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.

Cuddington homes and the weather
Historic houses like Waddesdon Manor (about 3.3 miles north) are a reminder that the area around Cuddington has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Parish Church of St Nicholas, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Haddenham & Thame Parkway station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Cuddington and Dinton CofE School, its window and door frames need their mastic kept sound, just like a home’s.
