How to look after the new joints

To keep the joints looking good and working properly:

  • Make sure downpipes are not blocked
  • Glance at the soffit joints now and then
  • Keep the gutters clear of debris
  • Watch for drips in a downpour

Leave the new sealant to cure as we advise before poking or cleaning near it.

Early sealing limits how much water hits the wall. If we find a bigger problem, we will tell you.

Gutter sealing in Naphill

A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs if the gutter is not damaged. We are often asked to deal with cracked sealant along roofline trims and leaking gutter joints and stop ends, across soffit joints, roofline trims and garage door frames.

Outside joints can only be sealed when they’re dry, so work in Naphill is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.

You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or email us.

Surface by surface

Soffit joints

Gaps at soffit joints can let in draughts and insects. We close them with a suitable sealant.

Roofline trims

We seal the trims, not the roof. A roofer deals with the roof itself.

DIY sealant or a professional job?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

Leave it or put it right?

A dripping stop end can soak the wall right through the wet months. It’s a small job to put right compared with treating damp later. Older cottages and farmhouses around Naphill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

What you get with us

What affects the quote in Naphill

The price is agreed before any work begins. It takes into account:

  • Whether there’s mould to deal with
  • How easy the joints are to reach
  • The amount of work
  • The number of rooms or windows

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

What to tell us for a quote

Photos help, but a description is a good start. Please mention:

  • A few pictures by email, if you can
  • The rough size of the job
  • How we’d reach the joints
  • If someone has resealed it before

It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you are ready, ring 0345 464 0079 or send us an email.

What we’re called out for in Naphill

A sealant applied to a damp or dirty joint will not bond. Some quick repairs peel off within a season or two for this reason.

Common reasons people contact us include:

  • Quick sealant fixes on gutters that didn’t last
  • Drips from gutter joints and end caps
  • Wet patches on the wall under a gutter joint
  • Fascia boards with gaps between them

For site and facilities teams at buildings such as Naphill and Walters Ash School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Before booking anyone

  • What the cure time is
  • Which colour the sealant will be
  • Is the old sealant removed completely?
  • Which sealant they’ll use, and why

Gutter sealing in Naphill: local notes

With historic houses such as Hughenden Manor (about 1.5 miles south-east) nearby, there’s older building stock in the area around Naphill as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Letting a property close to Saunderton 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 Church of St Botolph, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

FAQs for Naphill

Do you work for landlords with property near Saunderton station?

Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.

Will you come out to Naphill?

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.

Will you leave a mess?

We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.

Is there any odour?

There can be a smell while the sealant cures. Opening a window helps.

Will sealing fix a sagging gutter?

It won’t last. The movement opens the joint again so the gutter has to be refixed first.

Does someone need to be in?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Is it worth trying it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

What do you put in the joint?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

The process

All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. It normally takes a few hours, depending on the number of joints and the access. Somewhere as small as Naphill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by tracing the leak and checking the gutter itself is sound.
  2. We clean out the joint and take out the old sealant.
  3. The area is dried so the sealant can bond.
  4. We seal the joint with a sealant made for gutters and outdoor use.
  5. We look along the gutter and clear debris around the joints.

How to prepare

  • Let us know if you’ve seen damp or leaks
  • Mention any tricky access
  • For business premises, tell us about site rules or sign-in
