Window mastic in Spencers Wood: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Stratfield Saye House (about 3.3 miles south) are a reminder that the area around Spencers Wood has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Reading Green Park station, renewing tired window mastic between tenants heads off draught and damp complaints.

Window mastic in Spencers Wood
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for cracked internal joints between frame and plaster and whistling draughts around closed windows, across timber windows & doors, uPVC windows and composite doors.
Around Spencers Wood, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.

What we’re called out for in Spencers Wood
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
People generally contact us after spotting one of these:
- Whistling draughts around closed windows
- Cracked internal joints between frame and plaster
- Mastic that is falling out in pieces
- Rushed sealant from a window installation
In the older streets around St Michael and All Angels, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Before you book anyone
- Whether all the old sealant comes out first
- Whether VAT is included
- Whether you can choose the colour
- How the joint is cleaned and prepared
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
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.
Leave it or put it right?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Around Spencers Wood, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- A frame that has rotted at the joint
- Condensation trapped between the panes
- Damp coming through the wall itself rather than the frame joint
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before booking.
Surfaces we seal
- uPVC windows
- Aluminium frames

For landlords and businesses

Questions from Spencers Wood
Do you cover smaller places like Spencers Wood?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Reading Green Park station. Can you help?
Yes. We work for landlords and agents as well as householders. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Do you work on first-floor windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
How long does it take to reseal the windows on a house?
A few frames take a few hours, while a whole house takes longer. You’ll get a timescale with the quote.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or send us an email.
Can I paint over the new sealant?
Silicone generally will not take paint. Let us know beforehand, and we’ll use a paintable product where it suits.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames normally suit brown.
The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take most of a day for a typical house, less for a few frames. Parking around Spencers Wood is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First, we go round the frames with you and agree the list.
- 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.
Before we arrive
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in
- Clear items away from the joints we are working on

Advice
What affects the cost of window mastic
There’s no set price list. The quote depends on:
- Mould in or behind the old joints
- The product the joint needs
- The number and length of the joints
- Whether old sealant or filler has to be cut out
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.

- The rough size of the job
- Where the job is, and your postcode
- Any previous sealing or DIY work
- Photos by email, if that is easy
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you are ready, phone 0345 464 0079 or email us.
