Window & door mastic in East Wellow, Hampshire
Mastic around window and door frames, sills and patio doors for homes and businesses in East Wellow and across Hampshire. Fully insured, ARBOMaster approved and guaranteed for a year.
- Mastic that’s falling out in pieces
- Draughty joints inside around the window
- A bead that doesn’t match the frame
Window mastic in East Wellow, done properly
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. Typical jobs include hard, cracked sealant around windows and mastic that’s falling out in pieces, on aluminium frames, window sills and composite doors.
In a village or hamlet like East Wellow, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
A 12-month guarantee comes as standard.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens on the day
On the day, we start by going over the job with you. Surfaces next to the work are protected before work begins. The work usually takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as East Wellow, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Before we arrive
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we are working on

Windows and doors in East Wellow
With historic houses such as Landford Manor (about 2.8 miles west) nearby, there’s older building stock in the area around East Wellow as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Wellow School? Then larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of St Margaret, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. Around East Wellow, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts.

Aftercare tips
After the cure time, these simple habits help:
- Repaint timber before it’s bare
- Wipe condensation off the frames
- Keep solvents and bleach off the sealant
- Paint up to the joint, not over it
Try not to touch the new joint while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Do you need window mastic in East Wellow?
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
These are the problems we’re asked about most:
- White mastic on grey or black frames
- Black, perished sealant on frames
- Cracked or shrunken mastic around the frame
- Cracked sealant at the sill ends
For landlords with property near Romsey station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
