Outdoor sealant needs dry, clean surfaces, so work on frames around Blendworth is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

Why act early in Blendworth
Fixing a leaking screen early protects what’s underneath. Water from a failed joint can soak into the floor before you notice. Older cottages and farmhouses around Blendworth can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

What else we do in Blendworth

Shower screens
Frameless screens rely on silicone at the base and wall. We reseal without scratching the glass.
Signs you need glazing silicone in Blendworth
Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. That is why we trace the leak first.
Look out for any of the following:
- Split or lifting silicone on glass
- Black or yellowed silicone on glass joints
- Leaks where conservatory glass meets the frame
- New silicone smeared over old sealant
Rented homes near Rowlands Castle station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Avoid scraping close to the bead
- Inspect the sealant on glazing annually
- Squeegee the shower screen after each use
- Get a new leak looked at quickly
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix, before water gets in.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we’ll tell you which.
Glazing silicone in Blendworth: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Uppark (about 4.8 miles north-east) nearby, there’s older building stock in the area around Blendworth as well as newer homes. 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.
Schools such as Horndean Church of England Junior School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of the Holy Trinity, the joint between an old wall and a newer frame is usually the first place rain gets in.
Blendworth is about 1 mile north-east of Horndean, in Hampshire.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
