Window & door mastic in Bishop's Sutton, Hampshire
Problem with your window and door frames in Bishop's Sutton? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.

- Gaps left after new windows were fitted
Do you need window mastic in Bishop's Sutton?
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. Backing rod sets the right depth.
Keep an eye out for these signs:
- Sealant in the wrong colour for the frame
- Water coming in at the bottom corners of a door
- Draughty joints inside around the window
- Cracked or shrunken mastic around the frame
In the older streets around Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How we handle window mastic in Bishop's Sutton
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on patio & French doors, aluminium frames and uPVC windows, and common reasons people get in touch are water coming in at the bottom corners of a door and cracked internal joints between frame and plaster.
Homes in small places like Bishop's Sutton often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Our work is backed for twelve months.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
How the job changes by surface
Composite doors
Front doors take the weather head on. Those corners get the most care.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
FAQs for Bishop's Sutton
Will you come out to Bishop's Sutton?
Yes. Bishop's Sutton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is there a guarantee on window mastic in Bishop's Sutton?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.
Is the new sealant paintable?
It depends on the sealant. Silicone isn’t paintable, but some hybrid sealants are. Mention any painting plans before we start.
Do you work for letting agents?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
What happens if it’s left?
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around Bishop's Sutton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.

Window mastic in Bishop's Sutton: local notes
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. Historic houses like Hinton Ampner House (about 2.9 miles south) are a reminder that the area around Bishop's Sutton 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.
Managing a site like Perins School? Then its window and door frames need their mastic kept sound, just like a home’s.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Keep drainage slots and sill grooves clear
- Keep paint and stain on wooden frames in good order
- Use gentle cleaners on frames and sealant
- Keep solvents and bleach off the sealant
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or email us.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
