Gutter sealing in Dover

Garage door frames let rain in when the sealant around them fails. The frame joint is cut out and resealed using a sealant made for outdoor use. If you have water running down the wall below the gutter and damp patches inside below a leaking gutter, we can help, on soffit joints, gutter end caps and uPVC fascias alike.

Garage door frames, porches and roofline trims are all part of external work in a town like Dover. Each joint between different materials moves in its own way, so the sealant has to cope with that.

Your job is guaranteed for a year, as with all our work.

What we do, step by step

There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours, depending on the number of joints and the access. For a job in Dover, 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. First we agree which joints need sealing.
  2. We clean out each joint.
  3. We make sure everything is dry.
  4. We apply exterior or gutter sealant and finish it neatly.
  5. We check our work before we leave.

How to prepare

  • Keep children and pets away from the work area
  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any tricky access

Can I do it myself?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

How the job changes by surface

Garage door frames

Garage door frames let rain in when their sealant fails. It’s removed and renewed.

Soffit joints

Soffit board joints can separate over time. They’re sealed to tidy the line.

Why it’s worth doing now in Dover

Replacing guttering is a much bigger job than sealing joints. Where the gutter is in good order and only a joint leaks a reseal is all it needs. If it’s broken or sagging, a gutter installer needs to look. In Dover, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we will talk you through it.

How we quote for gutter sealing

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

  • The type of sealant required
  • Working hours on commercial sites
  • Whether old sealant or filler has to be cut out
  • The number of rooms or windows

Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

Asking for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • Pictures of the joints, sent by email
  • Whether it’s a home or a business
  • What the problem is, such as mould, gaps, leaks or cracking
  • How many joints, rooms or windows are involved

We do not publish a price list, because every job is different. Instead, we give you a clear quote for your job. To get started, ring 0345 464 0079 or drop us an email.

Dover buildings and the weather

Dover is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Schools such as Shatterlocks Infant School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Dover Priory 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 Parish Church of St Andrew Buckland, older walls, gutters and the joints where extensions meet them need a flexible sealant.
