Trusted gutter sealing in Fulwell

Keeping the joints in good condition

So the new joints stay in good condition:

  • Glance at the soffit joints now and then
  • Don’t lean ladders against the gutter itself
  • Clean out the gutters once or twice a year
  • Watch for drips in a downpour

Have a look at the gutter during a downpour. Drips are easiest to spot while it’s raining.

Split sealant on fascias and trims lets water in behind. Resealing early protects the boards.

Gutter sealing for homes and businesses in Fulwell

We do not replace gutters, fascias or roofs. What sealant does is close joints and it can’t mend broken brackets, split sections or blocked downpipes. We work on garage door frames, soffit joints and gutter joints, and people most often call us about quick sealant fixes on gutters that didn’t last and internal damp traced to a gutter joint.

In London terraces and converted houses, gutters and walls are often shared with the house next door, so a leaking gutter joint or failed wall joint can affect more than one home. For a flat in Fulwell, check the lease for who looks after the outside.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Should I try it myself first?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

How the visit works

All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take anything from an hour or two to a few hours. In Fulwell, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. We look at the gutters, fascias and trims and agree the joints to seal.
  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.

Before we arrive

  • Tell us about any previous sealing or DIY attempts
  • Clear items away from the joints we’re working on
  • Let us know if you’ve seen damp or leaks

When to call us in Fulwell

Overflowing gutters can look like leaking joints. A blocked downpipe makes water back up so we check the cause first.

If you can see any of these, it’s time to have the joints looked at:

  • Leaking gutter joints and stop ends
  • Open joints in fascias and soffits
  • Garage door frames letting rain in
  • Old gutter sealant that has let go

For landlords with property near Fulwell station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Questions to ask before you book

  • What insurance they hold
  • What the quote includes, VAT included or not
  • Is the old sealant removed completely?
  • What preparation is included

How to choose a mastic man

What happens if it’s left?

A new garage door isn’t needed for a leaking frame. Resealing the frame joint is often enough, if the frame itself is sound. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

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

Why us?

  • Any old sealant cut out fully, not covered over
  • A 12-month guarantee on all work
  • A sealant colour to suit the surroundings
  • You choose the colour before work begins

Fulwell buildings and the weather

London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Schools such as Stanley Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. As a London address, Fulwell can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
