Do you need gutter sealing in Dartford?

Sealant laid on a wet or dirty joint fails early. Some quick repairs peel off within a season or two for this reason.

Keep an eye out for any of the following:

  • Old sealant on roofline trims that has split
  • Drips from gutter joints and end caps
  • End caps that drip every time it rains
  • Gaps along fascia and soffit joints

If you look after a building such as Dartford Primary Academy, its movement joints, gutters and trims need looking after like any other building’s.

Questions to ask before you book

  • What happens if they find a problem under the old sealant
  • The length of the guarantee
  • When the joint can take water or movement
  • Who does the work, and how experienced they are

Gutter sealing in Dartford, done properly

Our work covers gutter joints and end caps as well as fascias and soffits, along with roofline trims and garage door frames. It’s all about the joints rather than new guttering. We work on gutter end caps, gutter joints and garage door frames, and common reasons people get in touch are cracked sealant along roofline trims and open joints in fascias and soffits.

Around Dartford, outside jobs take in garage door frames, porches, gutters and trims as well as walls. Where two materials meet, they move differently, and the sealant has to allow for it.

We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

How we quote for gutter sealing

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

  • The old material and how stubborn it is
  • How many areas need sealing
  • The number and length of the joints
  • Whether there’s mould to deal with

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

What to tell us for a quote

To make quoting easier, please include:

  • Any previous sealing or DIY work
  • The rough size of the job
  • A few pictures by email, if you can
  • Whether it’s a home or a business

Want a quote for gutter sealing? Please phone 0345 464 0079 or send us an email and tell us about the job. You will know what we plan to do, and what it will cost, before any work begins.

Aftercare tips

Joint life depends on how it’s used and looked after. We suggest:

  • Watch for drips in a downpour
  • Get a dropping gutter looked at quickly
  • Deal with a drip before winter
  • Clear leaves and moss from the gutters

Clear the gutters once or twice a year, so water drains away past the joints. Water left in a gutter tests every joint.

A leaking stop end is best sealed before the wet months. Water down the wall all winter can cause damp inside.

What happens on the day

At the end, we look at the finished work together. The work normally takes an hour or two for a few joints, longer for a full run, depending on the amount of work. For a job in Dartford, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.

  1. We find where the water is coming from and check the gutter is sound.
  2. The old sealant and dirt are cleaned out of the joint.
  3. We dry the joint so the new sealant can bond.
  4. We seal the joint with a sealant made for gutters.
  5. The gutter is checked and debris around the joints cleared.

Before we arrive

  • Keep pets and children clear of the area while we work
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any previous sealing or DIY attempts

Why deal with it now?

A new garage door isn’t needed for a leaking frame. Resealing the frame joint is often enough, if the frame itself is sound. Gaps in sealant and mould in the bead never get better on their own, and in a busy home in Dartford they get worse with every use. Now is the easy time to put it right.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Why us?

  • One-year guarantee on every job
  • We agree the colour with you first

Gutter sealing in Dartford: local notes

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hall Place and Gardens (about 2.8 miles west) are a reminder that the area around Dartford has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

Rented homes near Dartford station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. Homes close to Church of the Holy Trinity include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
