When to call us in Northfleet Green

Water spilling over a blocked gutter is often mistaken for a leak. If the downpipe is blocked, water has nowhere to go so we check the cause first.

People normally contact us when they notice one of these:

  • Quick sealant fixes on gutters that didn’t last
  • Streaks down the brickwork from a leaking joint
  • Failed sealant on a garage door frame
  • Damp patches inside below a leaking gutter

In the older streets around Church of St Nicholas, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Gutter sealing in Northfleet Green

Open fascia and soffit joints spoil the roofline and can let weather in. We seal them in a colour to suit where one is available. We work on garage door frames, gutter joints and roofline trims, and common reasons people get in touch are open joints in fascias and soffits and garage door frames letting rain in.

Around Northfleet Green, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in.

We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Why act early in Northfleet Green

A dripping gutter joint keeps wetting the same patch of wall. Left, it can stain walls and lead to damp, so it’s worth sealing early. Older cottages and farmhouses around Northfleet Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Walls and rooflines in Northfleet Green

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Cobham College (about 3.2 miles south-east) nearby, there’s older building stock in the area around Northfleet Green as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

If you look after a building such as Painters Ash Primary School, larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Ebbsfleet International station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.

Aftercare tips

A little care helps the new joints last. We recommend:

  • Look along the fascias for open joints
  • Watch the wall under the gutters for staining
  • Keep the gutters clear of debris
  • Get a dropping gutter looked at quickly

Make sure downpipes aren’t blocked, so water can get away. A blocked pipe backs water up to the joints.

Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall and that can cause damp inside.

Northfleet Green questions

Do you cover Northfleet Green for gutter sealing?

Yes. We work across London and the South East, and Northfleet Green is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.

Do you work for landlords with property near Ebbsfleet International station?

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

Do you offer different sealant colours?

Usually, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.

How long will you be here?

That depends on how much there is to do, but as a guide it takes an hour or two for a few joints, longer for a full run. We will give you a better idea when we quote.

Is it messy?

We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.

Do you remove the old sealant?

Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Is it OK to seal over old sealant?

No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Do you guarantee gutter sealing?

All our work carries a 12-month guarantee, and we’re fully insured.

Quotes for gutter sealing in Northfleet Green

Some jobs are bigger than they look, and some smaller. The main factors:

  • How easy the joints are to reach
  • Whether old sealant or filler has to be cut out
  • The product the joint needs
  • The amount of work

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. You will know the price before we begin.

Helping us quote

There’s no need for technical detail. It helps if you can tell us:

  • Where the property is
  • Whether it’s a home or a business
  • Access, such as stairs, a lift or height
  • The problem you’ve noticed

We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or drop us an email.

When something else is needed

We’d rather tell you now than do work that won’t last, so these are the limits:

  • Fascias that need replacing
  • Downpipes that are blocked or broken
  • Guttering that needs replacing

If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.

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: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

How the visit works

When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. The work generally takes an hour or two for a few joints, longer for a full run. Somewhere like Northfleet Green needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. First we agree which joints need sealing.
  2. We clean out each joint.
  3. The joints are dried.
  4. The sealant is applied and finished.
  5. We check our work before we leave.

Getting ready for the visit

  • Clear the area around the work
  • Let us know about stairs, lifts or work at height
  • Keep children and pets away from the work area
