Gutter sealing near Steventon

What affects the cost of gutter sealing

Jobs vary more than people expect. The main factors:

  • Any working-time requirements on site
  • Any mould that needs treating
  • How easy the joints are to reach
  • The size of the job

Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

What we need to know

Photos by email are helpful but not essential. Try to tell us:

  • Any previous sealing or DIY work
  • How we’d reach the joints
  • The type of property
  • What’s wrong with the joints now

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.

How we handle gutter sealing in Steventon

For gutter sealant to hold, the joint has to be clean and dry. So the old sealant and grime come out first, then dry the joint before sealing. If you have dripping gutter ends and damp patches inside below a leaking gutter, we can put it right, whatever the surface.

Older homes in small places like Steventon may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.

Big or small, it’s backed by our one-year guarantee.

When to call us in Steventon

Stop ends take pressure from water running along the gutter. Once the seal behind them fails, they drip and runs down the wall.

Look out for these signs:

  • Earlier gutter repairs that have peeled off
  • Water running down the wall below the gutter
  • Garage door frames letting rain in
  • Dripping gutter ends

For an older house near a landmark such as Church of St Michael and All Angels, an extension built onto an older house moves differently, and the joint between them takes the strain.

What your quote should include

  • Is the old sealant removed completely?
  • When the joint can take water or movement
  • Are they insured?
  • How the surfaces are prepared before sealing

Our hiring checklist

Steventon: your questions answered

I let a flat near Didcot Parkway station. Can you help?

Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.

Will you come out to Steventon?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Will sealing fix a sagging gutter?

Sealant will not hold a sagging gutter. The gutter needs refixing by a gutter installer.

Can a leaking gutter joint be sealed?

In most cases, yes. If the gutter is sagging or cracked, sealing won’t last, and we’ll tell you.

What should I tell you?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or send us an email.

Where are you based?

We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.

Are you ARBOMaster approved?

Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.

Can you match the sealant colour?

Generally, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before work begins.

What the job involves on each surface

Soffit joints

Gaps at soffit joints can let in draughts and insects. We close them with a suitable sealant.

uPVC fascias

Open fascia joints look untidy and can let water in. Sealing them closes the gap.

When it is not the sealant

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

  • Sagging gutters or broken brackets
  • Fascias that need replacing
  • Blocked downpipes

If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.

What we seal

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

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

What happens on the day

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on the number of joints and the access. In a small place like Steventon, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at where the water is coming from and check the gutter is not broken or sagging.
  2. The joint or trim is cleaned out and old sealant removed.
  3. The joint is dried, because sealant will not bond to a wet surface.
  4. Gutter or exterior sealant is applied and finished.
  5. The run is checked and any debris near the joints is cleared.

How to prepare

  • Keep pets and children clear of the area while we work
  • Let us know if you’ve seen damp or leaks
  • Mention any tricky access

The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Letting a property close to Didcot Parkway station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Looking after it afterwards

Looking after new joints is easy, and it makes a real difference:

  • Do not leave a sagging gutter
  • Keep downpipes clear
  • Watch for drips in a downpour
  • Keep the gutters clear of debris

Check the joints after heavy rain now and then. It’s the easiest time to see a leak.

Once roofline sealant splits, water can get behind it. Resealing early protects the boards and the wall below.
