Gutter sealing in Northfleet

How we handle gutter sealing in Northfleet

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 gutter end caps, gutter joints and roofline trims, and the jobs we see most are trim joints where the sealant has failed and old gutter sealant that has let go.

Around Northfleet, outside jobs take in garage door frames, porches, gutters and trims as well as walls. 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.

DIY versus a professional finish

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Looking after it afterwards

Good habits help new joints last longer. A few tips:

  • Deal with a drip before winter
  • Look for streaks or damp on the wall below gutters
  • Keep ladders off the guttering
  • Check that water runs out of the downpipes

While checking gutters, glance at the fascia joints too. A small split is quicker to put right.

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

For landlords and businesses

For anyone letting property in or around Northfleet, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

How the visit works

When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take anything from an hour or two to a few hours. Parking in a town like Northfleet is usually straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.

  1. First we trace the drip and check the gutter isn’t damaged.
  2. We remove the old sealant and clean the joint.
  3. We dry the joint so the new sealant can bond.
  4. A gutter sealant is applied to the joint.
  5. We check the run and clear debris near the joints.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • Clear the area around the work
  • For business premises, tell us about site rules or sign-in

Advice

When to call us in Northfleet

Gutter joints depend on seals that wear out. Temperature changes make gutters move and that movement opens up tired joints.

Signs it’s time to call us include:

  • Streaks down the brickwork from a leaking joint
  • Damp on an inside wall under a dripping gutter
  • Dripping gutter ends
  • Cracked sealant along roofline trims

Homes close to Church of All Saints include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What gutter sealing looks like in Northfleet

Northfleet is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on gutter, fascia and roofline joints, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

For site and facilities teams at buildings such as Northfleet Technology College, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Gravesend station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Common questions in Northfleet

Do you work for landlords with property near Gravesend station?

Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.

Does living near the coast affect gutter sealing in Northfleet?

Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.

Do I need to be at home?

We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.

Is sealant enough for a gutter that has dropped?

Not on its own. A sagging gutter pulls its joints apart, so the brackets need fixing first.

Are you fully insured?

Yes. We are fully insured.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

What guarantee comes with the job?

Our 12-month guarantee applies to all our work.

Can new sealant go over the old?

No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
