How we handle gutter sealing in Mortimer
A drip at a gutter joint is easy to ignore, but the water lands on the same spot every time it rains. Resealing it is a small job if the gutter is otherwise in good order. We work on gutter end caps, uPVC fascias and soffit joints, and the jobs we see most are end caps that drip every time it rains and failed sealant on a garage door frame.
In a smaller place like Mortimer, some homes face open ground, and walls and rooflines facing the weather take the worst of it. Joints on those sides are normally the first to go.
You get a 12-month guarantee, the same in Mortimer as everywhere else we work.

What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It generally takes an hour or two for a few joints, longer for a full run. For a job in Mortimer, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we find the drip and check the gutter is not cracked or sagging.
- The joint or trim is cleaned out and old sealant removed.
- We make sure the joint is dry before sealing.
- We seal the joint with a sealant made for gutters and outdoor use.
- We look along the gutter and clear debris around the joints.
How to prepare
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- Keep children and pets away from the work area

Why act early in Mortimer
You don’t need to replace a garage door because rain gets in round the frame. Sealing the frame usually stops it. Homes in smaller places like Mortimer can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Deal with a drip before winter
- Clear leaves and moss from the gutters
- Keep downpipes clear
- Look at the gutters while it’s raining
Clear the gutters once or twice a year so water doesn’t sit on the joints. Standing water strains every seal.
A leaking garage frame lets water reach stored items. Resealing the frame is a quick job while the frame is sound.
When it is not the sealant
A few problems are outside what sealant work can do:
- Boards that have decayed or split
- Blocked downpipes
- Cracked, split or warped gutter sections
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.

Gutter sealing in Mortimer: local notes
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. Historic houses like Stratfield Saye House (about 3.6 miles south-east) are a reminder that the area around Mortimer 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.
In the older streets around Mortimer Methodist Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like Mortimer St John's C.E. Infant School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Common problems we fix in Mortimer
Gutter joints rely on seals that age. Sun and cold make the gutter expand and contract, and old seals crack or slip.
Look out for any of the following:
- Gaps along fascia and soffit joints
- Trim joints where the sealant has failed
- Garage door frames letting rain in
- Quick sealant fixes on gutters that didn’t last
Rented homes near Mortimer station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.
