Windows and doors in Cuddington
Historic houses like Nonsuch Mansion (about 0.2 miles north-east) 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Cheam station, renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near Church of St Dunstan, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

About our window mastic in Cuddington
Homes in Cuddington have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on composite doors, uPVC windows and timber windows & doors, and people most often call us about mastic that has split away from the wall and leaking joints at the ends of sills.
Mastic can only go onto a dry, clean joint, so window work in Cuddington is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All our work comes with a 12-month guarantee, wherever you are in Surrey.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

What else we do in Cuddington
Common problems we fix in Cuddington
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. Backing rod sets the right depth.
Common reasons people contact us include:
- White mastic on grey or black frames
- Cracked or shrunken mastic around the frame
- Cold air getting in at the frame edge
- Gaps where the sill meets the wall
Managing a site like Nonsuch High School for Girls? Then the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- What the quote includes, VAT included or not
- Which sealant they’ll use, and why
- What insurance they hold
- How the joint is cleaned and prepared
What sealant work can’t fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Rotten timber, which needs a joiner first
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Draughts through the window seals rather than the frame
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.

Will resealing my frames help with draughts?
It will if the frame joint is the problem. We check where the draught is before any work starts.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.

What affects the cost of window mastic
Every job gets its own quote. These are the things that affect it:
- How many rooms, windows or areas are involved
- The size of the job
- Whether old sealant or filler has to be cut out
- Whether the work is at height
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we will talk you through it.

- Access, such as stairs, a lift or height
- A few pictures by email, if you can
- Whether it’s a home or a business

How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a few frames, or a day or more for a whole house. Somewhere like Cuddington needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Mention any tricky access
- Keep children and pets away from the work area
- Clear items away from the joints we are working on

Advice
How the job changes by surface
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
