About our gutter sealing in Preston Crowmarsh
Garage door frames let rain in when the sealant around them fails. We cut out the old sealant and reseal the frame using a sealant made for outdoor use. If you have gaps along fascia and soffit joints and old gutter sealant that has let go, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Preston Crowmarsh is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Big or small, it’s backed by our 12-month guarantee.

Can I do it myself?
If you are 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 doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
How the job changes by surface
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a quick reseal.
Roofline trims
We reseal trim joints with an exterior sealant suited to the material.

Signs you need gutter sealing in Preston Crowmarsh
Overflowing gutters can look like leaking joints. If the downpipe is blocked, water has nowhere to go, which is why we look before we seal.
If you can see any of these, it’s time to have the joints looked at:
- Old sealant on roofline trims that has split
- Wet patches on the wall under a gutter joint
- Leaking gutter joints and stop ends
- Dripping gutter ends
For landlords with property near Cholsey station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

What happens if it’s left?
A new garage door is not needed for a leaking frame. Resealing the frame joint is often enough, if the frame itself is sound. Around Preston Crowmarsh, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on the number of joints and the access and we leave things clean and tidy. For a village or hamlet like Preston Crowmarsh, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by tracing the leak and checking the gutter itself is sound.
- The joint or trim is cleaned out and old sealant removed.
- The joint is dried, because sealant will not bond to a wet surface.
- We seal the joint with a sealant made for gutters and outdoor use.
- We check the run and clear any debris we find while we are there.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we’re working on

Walls and rooflines in Preston Crowmarsh
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Brightwell Manor (about 2.4 miles west) nearby, there’s older building stock in the area around Preston Crowmarsh as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near Church of St Helen, older walls, gutters and the joints where extensions meet them need a flexible sealant. For site and facilities teams at buildings such as Benson Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.
