Window mastic in Goddington, done properly
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. To get one, ring 0345 464 0079 or email us with the number of frames and any access details for window mastic in Goddington. If you have whistling draughts around closed windows and cracked internal joints between frame and plaster, we can put it right, on uPVC windows, timber windows & doors and composite doors alike.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Goddington as anywhere.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

Goddington questions
Is parking a problem for a job in Goddington?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you cover Goddington for window mastic?
Yes, Goddington is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
How long should I leave it?
Cure times vary by product. We tell you how long to leave it before we go.
Does the work come with a guarantee?
Yes, with our one-year guarantee. A yearly look at the joints helps them last.
Are you fully insured?
Yes. We’re fully insured.
Where do you work from?
We work from Crawley. Our applicators cover Goddington.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
How it works
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. Expect the work to take anything from an hour or two to a full day, depending on how many frames there are, and we explain the cure time before we leave. In Goddington, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before

Other services in Goddington
Surface by surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Keep paint off silicone joints
- Keep solvents and bleach off the sealant
- Keep timber frames painted
- Use gentle cleaners on frames and sealant
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
What affects the quote in Goddington
The price is agreed before any work begins. It’s based on:
- Which sealant suits the joint
- How much there is to do
- The number of rooms or windows
- Mould in or behind the old joints
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear quote before we start.
Asking for a quote
Before you ask for a quote, have a think about:
- Where the job is, and your postcode
- Any previous sealing or DIY work
- Whether it’s a home or a business
- What’s wrong with the joints now
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or drop us an email.
When to call us in Goddington
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
If you can see any of these, it’s time to have the joints looked at:
- Mastic that’s falling out in pieces
- Cracked sealant at the sill ends
- Draughty joints inside around the window
- Untidy mastic left by window fitters
Schools such as The Highway Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
What to look for in a quote
- Which colour the sealant will be
- Whether they seal over old material or remove it
- How much experience the applicator has
- What the quote includes, VAT included or not
When something else is needed
We will not take on work that will not last, so here’s what sealant can’t put right:
- Soft or decayed wood in the frame
- Penetrating damp from a failed cavity tray or render
- A sash or casement that won’t close properly
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.
Surfaces we seal
- Timber windows & doors
- Patio & French doors
- Composite doors
- Aluminium frames
- uPVC windows
- Window sills
Window mastic in Goddington: local notes
With historic houses such as Down House (about 3.5 miles south-west) nearby, there’s older building stock in the area around Goddington as well as newer homes. 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.
If you let a flat or house near Chelsfield station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Homes close to Christ Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
