- Rushed sealant from a window installation
- A bead that does not match the frame
- Draughty joints inside around the window
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Do not paint over the silicone
- Make sure the drainage slots are not blocked
- Clean frames with a soft cloth and soapy water
- Keep paint and stain on wooden frames in good order
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
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.
Window mastic in Grazeley
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you are dealing with mastic that’s falling out in pieces and sealant in the wrong colour for the frame, we can help.
Outdoor sealant needs dry, clean surfaces, so work on frames around Grazeley is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
All of our work is guaranteed for twelve months, in Grazeley and everywhere else we cover.

What happens on the day
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for a handful of frames, longer for a whole house. Somewhere as small as Grazeley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

When to call us in Grazeley
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
Any of these means the joints need attention:
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
- A bead that doesn’t match the frame
- Draughts coming in around windows and doors
For site and facilities teams at buildings such as Grazeley Parochial Church of England Aided Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Your questions about window mastic in Grazeley
I let a flat near Reading Green Park station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Can you do window mastic in Grazeley?
Yes. Our work covers London and the South East, and Grazeley is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Can you quote for more than one area?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
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 will say so.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
Do you work on first-floor windows?
Yes, where it’s safe. For high or awkward windows, we will tell you what access is needed.
Do you seal inside as well as outside?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
What affects the quote in Grazeley
Some jobs are bigger than they look, and some smaller. The main factors:
- Working hours on commercial sites
- How easy the joints are to reach
- Any mould that needs treating
- How many areas need sealing
Combining jobs into one visit is generally more efficient than separate visits. We’ll give you a clear price for the lot.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- Where the job is, and your postcode
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can
For a quote, phone 0345 464 0079 or drop us an email with the location and a short description of the problem. We will give you a clear quote before any work starts.
Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Frames and glazing around Grazeley
With historic houses such as Stratfield Saye House (about 3.3 miles south) nearby, there’s older building stock in the area around Grazeley as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Reading Green Park station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Surface by surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
When it isn’t the sealant
Before you book, it’s worth knowing the limits:
- Condensation trapped between the panes
- Soft or decayed wood in the frame
- Draughts through the window seals rather than the frame
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
