Window mastic for homes and businesses in Tadley
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We work on uPVC windows, composite doors and timber windows & doors, and common reasons people get in touch are white mastic on grey or black frames and rushed sealant from a window installation.
In a town like Tadley, older houses sit alongside newer estates, with windows of every age. In every case, the joint between frame and wall is what keeps water out.
Big or small, you get the same one-year guarantee.

What we are called out for in Tadley
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Keep an eye out for these signs:
- White mastic on grey or black frames
- Black, perished sealant on frames
- Cracked or shrunken mastic around the frame
- Damp patches on the reveal after heavy rain
Homes close to Saint Mary's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What window mastic looks like in Tadley
London and the South East are among 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 The Vyne (about 4 miles south-east) are a reminder that the area around Tadley has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Midgham station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Bishopswood Junior School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

How the job changes by surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Why act early in Tadley
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In a family home in Tadley, a failed seal around a bath or a frame lets water into places you cannot see, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Landlords, agents and businesses in Tadley
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 that we can handle for you.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take most of a day for a typical house, less for a few frames. A visit in Tadley needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.

- Every joint is tooled smooth and checked before we leave.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Keep jet washers away from the mastic
- Clean frames with a soft cloth and soapy water
- Make sure the drainage slots are not blocked
- Repaint timber before it’s bare
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
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.
