About our window mastic in Coley Park
The new joint does not have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you have a bead that doesn’t match the frame and whistling draughts around closed windows, we can help, whatever the surface.
Homes around Coley Park range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Landlords, agents and businesses in Coley Park
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
Why it’s worth doing now in Coley Park
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. In a smaller place like Coley Park, 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.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

What else we do in Coley Park
Keeping the joints in good condition
Looking after new joints is easy:
- Keep paint and stain on wooden frames in good order
- Clear any debris from frame drain holes
- Do not paint over the silicone
- Avoid harsh chemicals near the mastic
Silicone can’t usually be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It generally takes a morning for a couple of windows and a door. For a job in Coley Park, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints

Coley Park homes and the weather
Historic houses like Mapledurham House (about 3.5 miles north-west) are a reminder that the area around Coley Park 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. Rainfall in the South East is lower than in much 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 Reading West station, renewing tired window mastic between tenants heads off draught and damp complaints. Managing a site like St Mary & All Saints Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as All Nations Christian Centre, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

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, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Your questions about window mastic in Coley Park
Can you help a landlord with a rental near Reading West station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do window mastic in Coley Park?
Yes, Coley Park is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
Will new mastic stop draughts?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. We will tell you how long your job needs when we quote.
Do you have sealant for grey or black windows?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames generally suit brown.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
