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 can talk through the options.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Window mastic in Godden Green
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. We work on uPVC windows, patio & French doors and composite doors, and people most often call us about draughts coming in around windows and doors and old mastic that has gone black or come away.
Somewhere as small as Godden Green, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Each job carries a 12-month guarantee, large or small.

Your questions about window mastic in Godden Green
Can you do window mastic in Godden Green?
Yes, Godden Green is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Is Godden Green within the area you cover?
Yes. Godden Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How much does window mastic cost in Godden Green?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or drop us an email and tell us what needs doing and where.
Do you have insurance?
Yes, we’re fully insured.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or email us.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that is a different fix, and we’ll say so.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Tell us if you’re decorating and we’ll choose accordingly.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we can’t put right
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Broken hinges, locks or handles
- Soft or decayed wood in the frame
- Damp coming through the wall itself rather than the frame joint
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Timber windows & doors
- Composite doors
- Patio & French doors
- Aluminium frames
- uPVC windows
- Window sills
Aftercare tips
After the cure time, these simple habits help:
- Ventilate rooms so frames do not stay wet inside
- Keep solvents and bleach off the sealant
- Do not paint over the silicone
- Clean frames with a soft cloth and soapy water
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or email us.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.
What happens on the day
We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes most of a day for a typical house, less for a few frames. Somewhere like Godden Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in

How we quote for window mastic
Every job gets its own quote. This is what makes a difference:
- The product the joint needs
- How much there is to do
- Whether the work is at height
- The old material and how stubborn it is
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us.
Asking for a quote
When you call or email, it’s useful to know:
- How many joints, rooms or windows are involved
- Where the job is, and your postcode
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, call 0345 464 0079 or drop us an email.
Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In a small place like Godden Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Window mastic in Godden Green: local notes

In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
