Looking after it afterwards

No joint lasts for ever, but care makes a real difference. Our tips:

  • Look at the gutters while it’s raining
  • Keep ladders off the guttering
  • Check that water runs out of the downpipes
  • Glance at the soffit joints now and then

While checking gutters, glance at the fascia joints too. Splits are easier to seal early.

Early sealing limits how much water hits the wall. If we find a bigger problem, we will tell you.

Gutter sealing in Greenford, done properly

We do not replace gutters, fascias or roofs. Sealant fixes joints and it can’t mend broken brackets, split sections or blocked downpipes. Common call-outs are for end caps that drip every time it rains and fascia boards with gaps between them, on roofline trims, garage door frames and gutter joints.

London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. For a flat in Greenford, check the lease for who looks after the outside.

You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Leave it or put it right?

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 has failed, we’ll tell you. In a flat in Greenford, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Why us?

  • 20+ years of sealant experience
  • ARBOMaster approved applicator
  • One-year guarantee on every job
  • 180+ five-star Google reviews

FAQs for Greenford

Can parking be tricky for a visit in Greenford?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.

Do you work for landlords with property near Greenford station?

Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint before applying anything new.

Can sealant stop a sagging gutter leaking?

No. A sagging gutter pulls its joints apart so it needs refixing before sealing.

Can you match the sealant colour?

We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.

Is gutter cleaning part of the job?

We clear what’s around the joints we work on. A full clean of the gutters isn’t part of it.

What about gutters on a second or third storey?

That depends on the building. Tell us the height and what’s around the gutter when you ring 0345 464 0079 or email us.

What information do you need?

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

What affects the cost of gutter sealing

The price is agreed before any work begins. It takes into account:

  • How many areas need sealing
  • The amount of work
  • Working hours on commercial sites
  • How easy the joints are to reach

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Asking for a quote

There’s no need for technical detail. It helps if you can tell us:

  • If it’s domestic, commercial or a hotel
  • Any access issues, like height or stairs
  • The problem you’ve noticed
  • Pictures of the joints, sent by email

Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we’ll talk you through the work and send you a clear quote.

Walls and rooflines in Greenford

With historic houses such as Northolt Manor (about 1 mile north-west) nearby, there’s older building stock in the area around Greenford as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

As a London address, Greenford can be tricky for parking: let us know about parking bays, permits or a driveway. Rented homes near Greenford station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Should I try it myself first?

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Signs you need gutter sealing in Greenford

Sagging sections pull joints apart. Sealing won’t hold if the gutter keeps dropping so the brackets need attention first.

The most common problems we see are:

  • End caps that drip every time it rains
  • Wet patches on the wall under a gutter joint
  • Internal damp traced to a gutter joint
  • Old sealant on roofline trims that has split

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