Window Mastic in Myrke
Window and door frames in Myrke need attention? We cut out the old, prepare the joints and apply the right sealant.
- Rain getting in at the frame or under the sill
- Rushed sealant from a window installation
- Old mastic that has gone black or come away
What the job involves on each surface
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
About our window mastic in Myrke
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. Typical jobs include draughts coming in around windows and doors and rain getting in at the frame or under the sill, on patio & French doors, composite doors and aluminium frames.
In a village or hamlet like Myrke, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, in Myrke and everywhere else we cover.

Signs you need window mastic in Myrke
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
If you can see any of these, it’s time to have the joints looked at:
- Mastic that has split away from the wall
- Cracked sealant at the sill ends
- Whistling draughts around closed windows
- Black, perished sealant on frames
For landlords with property near Slough station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Window mastic in Myrke: local notes
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. Historic houses like Windsor Castle (about 1.2 miles south-west) are a reminder that the area around Myrke has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Long Close School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Laurence include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.
Myrke is about 1 mile south-east of Slough, in Slough. Across the SL3 area, we cover window mastic for homes and businesses. Across Slough, we cover 31 places, Myrke among them. For nearby work, see our Reading page, about 17 miles away.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What happens on the day
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work starts. The work usually takes anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like Myrke, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions
- Mention if the joints have been sealed before

Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.

No. We work neatly, protect the area around the joints and tidy up afterwards.
Where do you work from?
We work from Crawley. Our applicators cover Myrke.
Is the work guaranteed?
Yes. Each job is covered for 12 months.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Looking after it afterwards
After the cure time, these simple habits help:
- Clear any debris from frame drain holes
- Paint up to the joint, not over it
- Keep timber frames painted
- Check the mastic once a year
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
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.
What affects the quote in Myrke
We don’t publish a price list, because no two jobs are the same. What we look at:
- How many areas need sealing
- The type of sealant required
- Mould in or behind the old joints
- Working hours on commercial sites
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- Where the job is, and your postcode
- The type of property
- Access, such as stairs, a lift or height
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
