Mastic around window and door frames, sills and patio doors for householders, landlords and businesses in Pyrton. Fully insured, ARBOMaster approved and guaranteed for a year.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Window mastic in Pyrton
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. Just ring 0345 464 0079 or email us and tell us how many frames there are and how they’re reached for window mastic in Pyrton. Typical jobs include damp patches on the reveal after heavy rain and white mastic on grey or black frames, across composite doors, uPVC windows and window sills.
Around Pyrton, 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 stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Pyrton homes and the weather
Historic houses like Adwell House (about 2.5 miles north) are a reminder that the area around Pyrton 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near St Mary's Church, the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as Watlington Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Different surfaces, different methods
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Why act early in Pyrton
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Older cottages and farmhouses around Pyrton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Check the mastic once a year
- Avoid harsh chemicals near the mastic
- Keep jet washers away from the mastic
- Wipe condensation off the frames
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
When it isn’t the sealant
It helps to know what we can’t do:
- Soft or decayed wood in the frame
- Penetrating damp from a failed cavity tray or render
- Faulty window hardware
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a morning for a couple of windows and a door for a typical job. Somewhere like Pyrton needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
