Gutter sealing in St Lawrence, done properly
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. They’re sealed in a matching colour where one is available. If you have old sealant on roofline trims that has split and gaps along fascia and soffit joints, we can put it right, on soffit joints, garage door frames and uPVC fascias alike.
Around St Lawrence, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

FAQs for St Lawrence
Can you help a landlord with a rental near Shanklin station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Is St Lawrence within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work on high-level gutters?
Single-storey work is the most straightforward. We’ll confirm the access for higher gutters once we know more.
Can you quote for more than one area?
Of course. Doing several areas at once is generally more efficient.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
Different surfaces, different methods
Soffit joints
Soffit board joints can separate over time. They’re sealed to tidy the line.
Roofline trims
Sealing roofline trims is joint work only. Roofing problems need a roofer.
What we can’t put right
We’d rather tell you now than do work that won’t last, so these are the limits:
- Problems with the roof covering
- Sagging gutters or broken brackets
- Fascias that need replacing
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.
Joints and surfaces we work on

What else we do in St Lawrence
Why deal with it now?
Replacing fascias because of open joints is usually unnecessary. Sealing the joints tidies them up if the boards are sound. Where a wall is exposed, as many are in small places like St Lawrence, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes an hour or two for a few joints, longer for a full run, depending on the size of the job. For a village or hamlet like St Lawrence, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Getting ready for the visit

- Plan for the work area to be out of bounds to pets and children

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep the gutters clear of debris
- Look at the gutters while it’s raining
- Keep downpipes clear
- Sort out a dripping joint early
Leave the new sealant to cure as we advise before poking or cleaning near it.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains, which can lead to staining and damp.
Landlords, agents and businesses in St Lawrence
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

Gutter sealing in St Lawrence: local notes
St Lawrence is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on gutter, fascia and roofline joints, especially on the side facing the sea. 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.
Schools such as St Francis Catholic and Church of England Primary Academy are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Shanklin station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. If you live in an older home near St Lawrence's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
