Gutter sealing for homes and businesses in Falconwood

Sealant only bonds to a clean, dry joint. That is why we take out the old sealant and dirt first, then dry the joint before sealing. Common call-outs are for damp on an inside wall under a dripping gutter and water running down the wall below the gutter, on uPVC fascias, garage door frames and soffit joints.

London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in Falconwood, it’s worth checking who is responsible for the outside before booking.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What happens on the day

A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. It usually takes an hour or two for a few joints, longer for a full run. In Falconwood, 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 where the water is coming from and check the gutter isn’t broken or sagging.
  2. The joint or trim is cleaned out and old sealant removed.
  3. The joint is dried, because sealant won’t bond to a wet surface.
  4. An exterior or gutter sealant is applied to the joint.
  5. We look along the gutter and clear debris around the joints.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • Mention any leaks or damp you’ve noticed
  • Mention any parking rules near the property

Work for landlords, hotels and businesses

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

If you manage several properties in or around Falconwood, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.

Why deal with it now?

If the problem is a blocked downpipe, sealing won’t help. We check the cause first and point you to the right trade if needed. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Falconwood, the repair is bigger than a sealant job.

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Falconwood buildings and the weather

Historic houses like Danson House (about 1 mile east) are a reminder that the area around Falconwood has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.

For site and facilities teams at buildings such as Bishop Ridley Church of England VA Primary School, its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Welling station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Do you need gutter sealing in Falconwood?

A sealant applied to a damp or dirty joint won’t bond. Rushed repairs often do not last long.

Look out for any of the following:

  • Earlier gutter repairs that have peeled off
  • Cracked sealant along roofline trims
  • Internal damp traced to a gutter joint
  • Gaps along fascia and soffit joints

If you live in an older home near Bishop Ridley Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Different surfaces, different methods

Roofline trims

We seal the trims, not the roof. Roofing problems need a roofer.

Gutter joints

When a joint drips, the gutter is often still sound. Sealing the joint often stops it.

Falconwood: your questions answered

Is Falconwood in your area for gutter sealing?

Yes, Falconwood is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.

Is parking a problem for a job in Falconwood?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.

Where are you based?

Our base is Crawley. Our area covers South East England, London and Scotland.

What do you put in the joint?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Are you insured?

Yes. We’re fully insured for domestic and commercial work.

Do you guarantee gutter sealing?

Every job comes with our 12-month guarantee.

Can you fit new guttering?

No. We seal leaking joints, end caps and trims. A gutter installer or roofer deals with replacement.

Do you seal gaps in fascias and soffits?

Yes. We seal the joints, not replace the boards and we will let you know if a board has failed.

Aftercare tips

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Rest ladders on the wall, not the gutter
  • Look for streaks or damp on the wall below gutters
  • Get leaks sealed before the wet months
  • Keep downpipes clear

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

A drip from a gutter joint won’t stop on its own. The same spot gets soaked every time it rains and that can cause damp inside.

When something else is needed

Before you book, it’s worth knowing the limits:

  • Leaks from the roof rather than a joint
  • Sagging gutters or broken brackets
  • Water backing up from a blocked pipe

If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
