Common problems we fix in Horseport
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
These are the problems we’re asked about most:
- Mastic round period door frames that has failed
- Mastic that needs renewing before redecorating
- Open joints round the window box
- Wind and rain getting in round a sash window
If you look after a building such as Fordingbridge Infant School, the mastic around its windows and doors needs looking after like any other building’s.

Sand mastic in Horseport
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead and we will explain which is best for yours. We’re often asked to deal with tired mastic found when preparing windows for paint and failed mastic on an exposed elevation, across timber door frames, tenement windows and brick reveals.
Homes in small places like Horseport 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What sealant work cannot fix
New sealant can’t fix everything, and we will tell you before we start. Sealant will not put right:
- Timber that has rotted
- Planning or listed building consent (your local planning authority decides)
- Crumbling stone or brickwork round the window

What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a single window, longer for several. For a village or hamlet like Horseport, 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 window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Clear items away from the joints we’re working on
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What sand mastic looks like in Horseport
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. With historic houses such as Breamore House (about 3 miles north) nearby, there’s older building stock in the area around Horseport as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as St Mary's Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

Why it’s worth doing now in Horseport
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a small place like Horseport, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Looking after it afterwards
To keep the joints looking good and working properly:
- Keep sills and gutters clear so water drains away
- Find out about consent before window work on a listed home
- Keep modern sealant off the mastic
- Have rotten timber repaired before new mastic goes in
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
