About our window mastic in Bowsey Hill
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. If you have mastic that has split away from the wall and a bead that doesn’t match the frame, we can help.
Mastic can only go onto a dry, clean joint, so window work in Bowsey Hill is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a few frames, or a day or more for a whole house and we leave things clean and tidy. In a small place like Bowsey Hill, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Clear items away from the joints we are working on
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can

When it is not the sealant
We won’t take on work that won’t last, so these are the limits:
- A failed sealed unit that has misted up
- Damp problems in the wall away from the window
- A frame that has rotted at the joint
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
What we seal
- Patio & French doors
- Aluminium frames
- uPVC windows
- Composite doors
- Window sills
- Timber windows & doors
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too in Bowsey Hill and across Wokingham. We can quote a run of properties together, and we’re fully insured.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Repaint timber before it’s bare
- Walk round the house once a year and look at the joints
- Avoid harsh chemicals near the mastic
- Clean frames with a soft cloth and soapy water
Try not to touch the new joint while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’re 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.
What affects the cost of window mastic
We quote each job individually. This is what makes a difference:
- The size of the job
- The number of rooms or windows
- Any working-time requirements on site
- Any mould that needs treating
Doing several joints on one visit is normally more efficient than separate visits. We’ll give you a clear price for the lot.
Helping us quote
You don’t need to know the technical terms. It helps if you can tell us:
- How many joints, rooms or windows are involved
- The type of property
- What’s wrong with the joints now
- The address or postcode of the job
If you are in Bowsey Hill and need window mastic, ring 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and you’ll get a clear quote before we start.
Signs you need window mastic in Bowsey Hill
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
People generally contact us when they notice something like this:
- Cracked sealant at the sill ends
- Cold air getting in at the frame edge
- Draughty joints inside around the window
- A bead that doesn’t match the frame
Homes close to St Paul's Mission Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

I let a flat near Wargrave station. Can you help?

Can you work on commercial sites?

Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
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.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Frames and glazing around Bowsey Hill
Historic houses like Harleyford Manor (about 3.3 miles north-east) are a reminder that the area around Bowsey Hill 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Crazies Hill CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Wargrave station, renewing tired window mastic between tenants heads off draught and damp complaints.
