Window mastic for homes and businesses in Sherfield English
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you have cracked sealant at the sill ends and black, perished sealant on frames, we can help, on window sills, composite doors and patio & French doors alike.
Around Sherfield English, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All our work comes with a one-year guarantee, wherever you are in Hampshire.

How the job changes by surface
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so they get particular care.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Keep paint and stain on wooden frames in good order
- Avoid blasting the frames with a pressure washer
- Air rooms to keep condensation down around windows
- Clear any debris from frame drain holes
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Windows and doors in Sherfield English
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. With historic houses such as Landford Manor (about 2.2 miles south-west) nearby, there’s older building stock in the area around Sherfield English as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St Leonard include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

- Broken hinges, locks or handles
- Condensation trapped between the panes

How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Sherfield English, 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.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Before we arrive
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Related advice
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Why it’s worth doing now in Sherfield English
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you. Where a wall is exposed, as many are in small places like Sherfield English, wind-driven rain gets into any failed joint, 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. You’ll know the price before we begin.

Yes, Sherfield English is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing.

Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Is the new sealant paintable?
That depends on the product. Silicone isn’t paintable, but some hybrid sealants are. Mention any painting plans before any work starts.

What does window mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
How long does it take to reseal the windows on a house?
Allow a few hours for a few frames, or a day or more for a whole house. Access and the amount of old mastic make the biggest difference.
What we are called out for in Sherfield English
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That is what backing rod is for.
Look out for these signs:
- Hard, cracked sealant around windows
- Gaps between the frame and the inside reveal
- Gaps where the sill meets the wall
- Rain getting in at the frame or under the sill
If you let a flat or house near Mottisfont & Dunbridge station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
