Gutter sealing for Bandonhill homes and businesses

Outside joints around Bandonhill

London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. With historic houses such as Addington Palace (about 4 miles east) nearby, there’s older building stock in the area around Bandonhill as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.

Addington Palace, about 4 miles east, is one of the historic houses in the wider area around Bandonhill, and older homes nearby need a sealant that suits their walls. For landlords with property near Waddon station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

About our gutter sealing in Bandonhill

Garage door frames let rain in when the sealant around them fails. The frame joint is cut out and resealed with an exterior sealant. We work on gutter end caps, roofline trims and uPVC fascias, and common reasons people get in touch are gaps along fascia and soffit joints and end caps that drip every time it rains.

In London terraces and converted houses, gutters and walls are often shared with the house next door, so one failed joint can cause damp for more than one household. In a converted house in Bandonhill, it’s worth checking who is responsible for the outside before booking.

Each job carries a 12-month guarantee, large or small.

How we quote for gutter sealing

The price is agreed before any work begins. It’s based on:

  • The product the joint needs
  • Any working-time requirements on site
  • How much there is to do
  • How many areas need sealing

Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

What we need to know

When you call or email, these details help:

  • Any previous sealing or DIY work
  • The type of property
  • Roughly how big the job is
  • The address or postcode of the job

We quote each job on its own. Just ring 0345 464 0079 or send us an email with the details, and pictures are welcome.

Aftercare tips

Good habits help new joints last longer. A few tips:

  • Rest ladders on the wall, not the gutter
  • Clear leaves and moss from the gutters
  • Do not leave a sagging gutter
  • Look for streaks or damp on the wall below gutters

Clear the gutters once or twice a year, so water drains away past the joints. Standing water strains every seal.

Rain getting in round a garage door frame can damage what’s stored inside. Resealing the frame is a quick job.

Bandonhill: your questions answered

Is parking an issue for gutter sealing in Bandonhill?

In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.

Do you cover Bandonhill for gutter sealing?

Yes. We work across London and the South East, and Bandonhill is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.

Will sealant fix a dripping gutter joint?

Yes, as long as the gutter itself is in good order. We clean and dry the joint before sealing so the sealant bonds.

Can I add another job to the visit?

Yes. Tell us about everything you’d like done and you will get one quote.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

What do you need from me for a quote?

The location, the problem and the rough size of the job. Photos by email help too.

How long will you be here?

Most jobs take anything from an hour or two to a few hours. We will confirm how long when we quote.

Is gutter cleaning part of the job?

We clear debris near the joints because the joint must be clean. A full gutter clean is a separate job.

What the job involves on each surface

Roofline trims

Trims along the roofline are often finished with sealant. Split sealant lets water in.

uPVC fascias

Fascia board joints can open up. We seal them neatly in a suitable colour.

DIY versus a professional finish

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

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.

When to call us in Bandonhill

End caps get knocked or pushed by water. Once the seal behind them fails, they drip and runs down the wall.

These are the problems we are asked about most:

  • Old sealant on roofline trims that has split
  • Water running down the wall below the gutter
  • Fascia boards with gaps between them
  • Damp on an inside wall under a dripping gutter

As a London address, Bandonhill can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.

For anyone letting property in or around Bandonhill, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.

How it works

On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take an hour or two for a few joints, longer for a full run. In Bandonhill, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

  1. We start by tracing the leak and checking the gutter itself is sound.
  2. Old sealant and dirt are removed from the joint.
  3. The area is dried so the sealant can bond.
  4. An exterior or gutter sealant is applied to the joint.
  5. We look along the gutter and clear debris around the joints.

How to prepare

  • Tell us about any previous sealing or DIY attempts
  • Let us know about parking restrictions
  • Mention any sign-in or site rules at work premises
