About our gutter sealing in Dedham

Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. We seal them in a colour to suit where one is available. We’re often asked to deal with failed sealant on a garage door frame and streaks down the brickwork from a leaking joint, across roofline trims, garage door frames and uPVC fascias.

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

We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Leave it or put it right?

A new garage door is not needed for a leaking frame. Resealing the frame joint is often enough, if the frame itself is sound. Where a wall is exposed, as many are in small places like Dedham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

Take a look at our cost guide and what customers say.

Common problems we fix in Dedham

When a gutter sags, its joints open. Resealing a sagging joint will not last so the brackets need attention first.

Look out for these signs:

  • Trim joints where the sealant has failed
  • Fascia boards with gaps between them
  • End caps that drip every time it rains
  • Streaks down the brickwork from a leaking joint

For site and facilities teams at buildings such as Dedham Church of England Voluntary Controlled Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What your quote should include

  • What happens if the job turns out different
  • How the surfaces are prepared before sealing
  • How much experience the applicator has
  • Are they insured?

10 questions to ask before you book

Dedham buildings and the weather

Historic houses like Castle House (about 0.5 miles south-east) are a reminder that the area around Dedham has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Rented homes near Manningtree station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls. For an older house near a landmark such as Parish Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Honest limits

New sealant can’t fix everything, and we’ll tell you before any work starts. Sealant will not put right:

  • A gutter length that has split
  • Rotten or damaged fascia boards
  • Downpipes that are blocked or broken

Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.

Joints and surfaces we work on

  • uPVC fascias
  • Soffit joints
  • Gutter joints
  • Roofline trims
  • Gutter end caps
  • Garage door frames

How we quote for gutter sealing

We don’t publish a price list. The quote depends on:

  • The size of the job
  • Whether the work is at height
  • Whether there’s mould to deal with
  • How much old sealant there is and how hard it is to remove

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Helping us quote

There’s no need for technical detail. Just tell us:

  • How we’d reach the joints
  • The rough size of the job
  • Where the property is
  • What’s wrong with the joints now

It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, ring 0345 464 0079 or drop us an email.

Aftercare tips

To keep the joints looking good and working properly:

  • Get a dropping gutter looked at quickly
  • Rest ladders on the wall, not the gutter
  • Look for streaks or damp on the wall below gutters
  • Glance at the soffit joints now and then

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 garage frame lets water reach stored items. A reseal sorts it.

How the visit works

When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins.

For a village or hamlet like Dedham, the journey is planned in advance: 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 trace the drip and check the gutter isn’t damaged.
  2. The old sealant and dirt are cleaned out of the joint.
  3. We dry the joint so the new sealant can bond.
  4. A gutter sealant is applied to the joint.
  5. The gutter is checked and debris around the joints cleared.

  • Let us know about stairs, lifts or work at height
  • Clear items away from the joints we’re working on
