Window mastic in Riseley
Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. Typical jobs include cold air getting in at the frame edge and water coming in at the bottom corners of a door, on timber windows & doors, patio & French doors and composite doors.
Around Riseley, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What we do, step by step
At the end, we look at the finished work together. The visit itself usually takes a few hours for a few frames, or a day or more for a whole house, depending on how much there is to do. Somewhere as small as Riseley, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in

Different surfaces, different methods
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.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.
Questions from Riseley
Is Riseley in your area for window mastic?
Yes. We work across London and the South East, and Riseley is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear quote.
Will you come out to Riseley?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is there any odour?
There can be a smell while the sealant cures. Opening a window helps.
Is the work guaranteed?
Yes. Our one-year guarantee covers every job, inside or out.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
How many windows can you do in a day?
Allow anything from an hour or two to a full day, depending on how many frames there are. Access and the amount of old mastic make the biggest difference.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Clean frames with a soft cloth and soapy water
- Do not aim a pressure washer at the joints
- Keep drainage slots and sill grooves clear
- Check the mastic once a year
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
When it is not the sealant
We will not take on work that will not last, so these are the limits:
- A failed sealed unit that has misted up
- Damp coming through the wall itself rather than the frame joint
- A frame that has rotted at the joint
If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

Why it’s worth doing now in Riseley
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly. In a small place like Riseley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

What window mastic looks like in Riseley
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Stratfield Saye House (about 1.7 miles south-west) nearby, there’s older building stock in the area around Riseley as well as newer homes. 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.
Rented homes near Mortimer station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
