Window mastic for homes and businesses in Marsh Benham
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We are often asked to deal with gaps left after new windows were fitted and cold air getting in at the frame edge, across uPVC windows, window sills and composite doors.
In a village or hamlet like Marsh Benham, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Condensation trapped between the panes
- Soft or decayed wood in the frame
- A sash or casement that won’t close properly

The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours for a few frames, or a day or more for a whole house. In a small place like Marsh Benham, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property

Why act early in Marsh Benham
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. If we find failed glass units or worn seals, we will tell you. Where a wall is exposed, as many are in small places like Marsh Benham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before work begins.

Landlords, agents and businesses in Marsh Benham
Landlords and agents in Marsh Benham can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
What the job involves on each surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. If we find rot, we will tell you before going ahead, as that’s a job for a joiner.
Aluminium frames
Coated aluminium needs a compatible sealant. We use a neutral-cure product.
Aftercare tips
After the cure time, these simple habits help:
- Don’t aim a pressure washer at the joints
- Make sure the drainage slots are not blocked
- Do not paint over the silicone
- Look round the frames every year or so
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.

How long will my window job take?
Allow a morning for a couple of windows and a door. Access and how stubborn the old mastic is affect the time most.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Is the new sealant paintable?
Silicone generally won’t take paint. Let us know beforehand, and we’ll use a paintable product where it suits.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
How much does window mastic cost in Marsh Benham?
Size, access and the old material all affect the cost. Call for a quick quote.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Marsh Benham homes and the weather
The South East is one of 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 Benham Park (about 0.7 miles east) are a reminder that the area around Marsh Benham 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.
Rented homes near Kintbury station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Church of St John, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Stockcross C.E. School? Then its window and door frames need their mastic kept sound, just like a home’s.
