DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
What affects the quote in Bisham
For a quick quote, just ask. The main things that affect it are:
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- Whether the work is at height
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Why it’s worth doing now in Bisham
Sealing over a dirty, wet joint is a quick fix that rarely lasts, but it soon lets go. Cleaning out and drying the joint first is what makes it last. Older cottages and farmhouses around Bisham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Gutter sealing in Bisham: local notes
Historic houses like Harleyford Manor (about 1.5 miles west) are a reminder that the area around Bisham has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like Bisham Church of England Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Marlow station, leaking gutter joints on a rental are best caught before they stain the walls.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Keep the gutters clear of debris
- Glance at the soffit joints now and then
- Rest ladders on the wall, not the gutter
- Keep downpipes clear
Look at fascia and trim joints when you are checking the gutters. A small split is quicker to put right.
A drip from a gutter joint will not stop on its own. Water keeps hitting the same part of the wall and that can cause damp inside.
