Gutter Sealing in Havant
We cover Havant for sealing leaking gutter joints, end caps, fascias, soffits and roofline trims. Old sealant removed completely, joints prepared properly.
- Water running down the wall below the gutter
- Garage door frames letting rain in
- Leaking gutter joints and stop ends
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
If you manage several properties in or around Havant, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.
How we handle gutter sealing in Havant
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. If you’re dealing with damp on an inside wall under a dripping gutter and drips from gutter joints and end caps, we can help.
Garage door frames, porches and roofline trims are all part of external work in a town like Havant. Each joint between different materials moves in its own way, so the sealant has to cope with that.
There’s a 12-month guarantee on every job, large or small.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Rest ladders on the wall, not the gutter
- Glance at the soffit joints now and then
- Get a dropping gutter looked at quickly
- Deal with a drip before winter
Leave the new sealant to cure as we advise before poking or cleaning near it.
Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall, which can lead to staining and damp.
What affects the quote in Havant
We don’t publish a price list, because jobs vary so much. The quote depends on:
- Whether there’s mould to deal with
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
Homes and businesses are quoted the same way: 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 explain what it covers.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:

What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take an hour or two for a few joints, longer for a full run. A visit in Havant needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.
- We look at the gutters, fascias and trims and agree the joints to seal.
- We clean out each joint.
- We make sure everything is dry.
- The sealant is applied and finished.
- We check our work before we leave.
How to prepare
- On commercial sites, let us know about site rules

When to call us in Havant
Sagging sections pull joints apart. Resealing a sagging joint will not last, so the gutter needs refixing first.
If you can see any of these, it’s time to have the joints looked at:
- Leaking gutter joints and stop ends
- Trim joints where the sealant has failed
- Internal damp traced to a gutter joint
- Open joints in fascias and soffits
If you live in an older home near St Francis, an extension built onto an older house moves differently, and the joint between them takes the strain.
What your quote should include
- What happens if they find a problem under the old sealant
- What the cure time is
- Whether all the old sealant comes out first
- Whether VAT is included
Why act early in Havant
New gutters cost far more than a few resealed joints. Where the gutter is in good order and only a joint leaks a reseal is all it needs. If it has failed, we’ll tell you. Around Havant, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Left alone, that means rot, damp and a bigger repair.

Walls and rooflines in Havant
Havant 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. Historic houses like Warblington Castle (about 1.5 miles south-east) are a reminder that the area around Havant 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.
Managing a site like Trosnant Infant School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Havant station, leaking gutter joints on a rental are best caught before they stain the walls.

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
