How we handle window mastic in Trotton Marsh
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. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you’re dealing with gaps between the frame and the inside reveal and leaking joints at the ends of sills, we can put it right.
Outdoor sealant needs dry, clean surfaces, so work on frames around Trotton Marsh is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
All our work comes with our 12-month guarantee.

Window mastic in Trotton Marsh: 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 Cowdray House (about 4.2 miles south-east) are a reminder that the area around Trotton Marsh 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.
For landlords with property near Liphook station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What affects the cost of window mastic
Every job gets its own quote. These are the things that affect it:
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- The size of the job
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Whether it has been sealed before
- Whether it’s a home or a business
- The rough size of the job
- What’s wrong with the joints now
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work before giving you a price.
Signs you need window mastic in Trotton Marsh
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.
It’s worth asking for a quote if you see:
- Cracked internal joints between frame and plaster
- Water coming in at the bottom corners of a door
- Mastic that has split away from the wall
- Black, perished sealant on frames
Historic houses such as Cowdray House, about 4.2 miles south-east, show how far back building around Trotton Marsh goes, and older homes nearby need a sealant that suits their walls.
Before you book anyone
- Which sealant they’ll use, and why
- How the joint is cleaned and prepared
- What the cure time is
- Whether all the old sealant comes out first
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Don’t aim a pressure washer at the joints
- Look round the frames every year or so
- Paint up to the joint, not over it
- Clear any debris from frame drain holes
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
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 early resealing is worth it.
Landlord and commercial work in Trotton Marsh
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Letting agents and landlords in Trotton Marsh can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
DIY sealant or a professional job?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes most of a day for a typical house, less for a few frames. Somewhere as small as Trotton Marsh, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
How to prepare
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
