Gutter sealing for homes and businesses in Lagness
Gutter and fascia replacement isn’t our trade, and nor is roofing. What sealant does is close joints; it will not fix a broken bracket, a cracked section or a blocked downpipe. We work on uPVC fascias, roofline trims and gutter joints, and people most often call us about quick sealant fixes on gutters that didn’t last and dripping gutter ends.
Somewhere as small as Lagness, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Surface by surface
Roofline trims
Roofline trims rely on sealant at their joints. Split sealant lets water in.
Garage door frames
Failed sealant around a garage door frame lets water in. It’s removed and renewed.
What affects the quote in Lagness
Jobs vary more than people expect. What affects the quote:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- The type of sealant required
- The number of rooms or windows
What you pay reflects the work, not guesswork. That is why we ask about the job first and send you a clear quote before we start.
What we need to know
Photos help, but a description is a good start. Please mention:
- The rough size of the job
- Access, such as stairs, a lift or height
- A few pictures by email, if you can
- If someone has resealed it before
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Don’t lean ladders against the gutter itself
- Watch the wall under the gutters for staining
- Watch for drips in a downpour
- Clean out the gutters once or twice a year
Keep downpipes clear so the gutter can drain. A blocked pipe backs water up to the joints.
Once roofline sealant splits, water can get behind it. Sealing it early keeps the boards behind dry and the wall below.
What we’re called out for in Lagness
Gutter joints depend on seals that wear out. Sun and cold make the gutter expand and contract and that movement opens up tired joints.
Keep an eye out for any of the following:
- Fascia boards with gaps between them
- End caps that drip every time it rains
- Trim joints where the sealant has failed
- Damp on an inside wall under a dripping gutter
For site and facilities teams at buildings such as Rose Green Junior School, larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- How the joint is cleaned and prepared
- Whether the sealant suits the joint
- Whether VAT is included
- Whether all the old sealant comes out first

Lagness buildings and the weather
Lagness is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on gutter, fascia and roofline joints, especially on the side facing the sea. Historic houses like Goodwood House (about 4.9 miles north) are a reminder that the area around Lagness 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.
Homes close to Church of St Giles include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Bognor Regis station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
Lagness is about 2 miles west of Bognor Regis, in West Sussex.

What we do, step by step
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours, depending on the number of joints and the access, and we explain the cure time before we leave. In a small place like Lagness, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at where the water is coming from and check the gutter isn’t broken or sagging.
- Old sealant and dirt are removed from the joint.
- The area is dried so the sealant can bond.
- 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’re there.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children

Lagness: your questions answered
Do you cover smaller places like Lagness?
Yes. Lagness is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Does the coastal weather in Lagness affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you work on high-level gutters?
That depends on the building. Let us know the height and the ground below when you call 0345 464 0079 or email us.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
Are you insured?
Yes. We are fully insured for every job we do.
What does gutter sealing cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you offer different sealant colours?
Most of the time, yes. We’ll explain which colours are available.
Can new sealant go over the old?
No, and we never do. 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.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
