Gutter sealing in Lumley
A drip at a gutter joint is easy to ignore, but each shower sends water to the same place. Resealing it is a small job while the gutter is still sound. We are often asked to deal with fascia boards with gaps between them and internal damp traced to a gutter joint, across uPVC fascias, soffit joints and garage door frames.
External sealant needs dry, clean surfaces, so work around Lumley is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Why deal with it now?
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp, so it’s worth sealing early. In a small place like Lumley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Walls and rooflines in Lumley
Lumley is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on gutter, fascia and roofline joints, especially on the side facing the sea. With historic houses such as Warblington Castle (about 1.6 miles west) nearby, there’s older building stock in the area around Lumley as well as newer homes. Where a home is older, 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 James, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like St James Church of England Controlled Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

A gutter joint has to cope with movement and standing water. A gutter sealant made for the job holds best.

What affects the cost of gutter sealing
You will get a clear quote before any work starts. It’s based on:

- The problem you’ve noticed
- Any access issues, like height or stairs

- How many joints, rooms or windows are involved

Common questions in Lumley
Is Lumley within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Emsworth station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Will sealing fix a sagging gutter?
Not for long. The movement opens the joint again, so the fall and brackets need sorting first.
Do you install new fascias or gutters?
No. Our work is sealing joints and replacement is a job for an installer.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes an hour or two for a few joints, longer for a full run. Somewhere like Lumley needs a little journey planning: 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.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
How to prepare
