When to call us in Emmer Green
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
It’s worth asking for a quote if you see:
- Cracked or shrunken mastic around the frame
- Draughts coming in around windows and doors
- Untidy mastic left by window fitters
- Gaps where the sill meets the wall
If you live in an older home near St Barnabas Church Hall, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What to look for in a quote
- What happens if they find a problem under the old sealant
- What the cure time is
- Whether VAT is included
- How the joint is cleaned and prepared
About our window mastic in Emmer Green
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on aluminium frames, timber windows & doors and uPVC windows, and common reasons people get in touch are mastic that’s falling out in pieces and cracked or shrunken mastic around the frame.
In a smaller place like Emmer Green, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.

What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes most of a day for a typical house, less for a few frames. For a job in Emmer Green, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints

How the job changes by surface
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. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
Your questions about window mastic in Emmer Green
Do you cover Emmer Green for window mastic?
Yes, Emmer Green is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
I let a flat near Reading station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we will plan for it.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
Is the new sealant paintable?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Tell us if you’re decorating and we’ll choose accordingly.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We check where the draught is before we start.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

- Draughts through the window seals rather than the frame

What affects the cost of window mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- How easy the joints are to reach
- The number and length of the joints
- Which sealant suits the joint
- Whether there’s mould to deal with
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- If someone has resealed it before
- Pictures of the joints, sent by email
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, call 0345 464 0079 or drop us an email.
Why it’s worth doing now in Emmer Green
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. In a smaller place like Emmer Green, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Windows and doors in Emmer Green
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Mapledurham House (about 3.2 miles west) are a reminder that the area around Emmer Green 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.
Schools such as The Hill Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Reading station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
