Need gutter sealing in Selhurst?

Can I do it myself?

If you’re 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 doesn’t work out, we can still put it right.

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.

About our gutter sealing in Selhurst

Open fascia and soffit joints spoil the roofline and can let weather in. We seal them in a colour to suit where possible. If you’re dealing with damp on an inside wall under a dripping gutter and trim joints where the sealant has failed, we can put it right.

Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.

The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Why act early in Selhurst

New gutters cost far more than a few resealed joints. Where the gutter is in good order and only a joint leaks a reseal is all it needs. If it’s broken or sagging, a gutter installer needs to look. In a flat in Selhurst, 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.

What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

Aftercare tips

To keep the joints looking good and working properly:

  • Keep downpipes clear
  • Have sagging gutters refixed early
  • Rest ladders on the wall, not the gutter
  • Clear leaves and moss from the gutters

Give the sealant the cure time we tell you before poking or cleaning near it.

A drip from a gutter joint will not stop on its own. Water keeps hitting the same part of the wall, which can lead to staining and damp.

Selhurst questions

Can you do gutter sealing in Selhurst?

Yes. Our work covers London and the South East, and Selhurst is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.

Can parking be tricky for a visit in Selhurst?

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

Do you take out the old sealant first?

Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.

Do you clean gutters?

We clear debris around the joints we’re sealing. Full gutter cleaning is a separate job.

What do you put in the joint?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.

What information do you need?

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.

Does someone need to be in?

We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.

Walls and rooflines in Selhurst

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. London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts.

Schools such as St Mark's Church of England Primary Academy are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Norwood Junction station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls. As a London address, Selhurst can be tricky for parking: let us know about parking bays, permits or a driveway.

What we can’t put right

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Guttering that needs replacing
  • Gutters that have dropped or pulled away
  • Leaks from the roof rather than a joint

If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

What we seal

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

What happens on the day

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a few hours, and the area is left clean. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.

  1. First we trace the drip and check the gutter is not damaged.
  2. The old sealant and dirt are cleaned out of the joint.
  3. The joint is dried before sealing.
  4. A gutter sealant is applied to the joint.
  5. We check the run and clear debris near the joints.

Preparing for the visit

  • Mention any tricky access
  • Mention any parking rules near the property
  • Try not to wet indoor joints just before the visit

Advice

How the job changes by surface

Gutter joints

Most gutter leaks start at a joint between sections. We clean, dry and reseal them.

Gutter end caps

Stop ends hold back water at the end of a run. When their seal fails, they drip.
