About our gutter sealing in Radnage

A drip at a gutter joint is easy to ignore, but each shower sends water to the same place. Resealing it is a small job if the gutter is otherwise in good order. We work on uPVC fascias, gutter end caps and garage door frames, and the jobs we see most are gaps along fascia and soffit joints and old gutter sealant that has let go.

Somewhere as small as Radnage, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.

Each job carries a 12-month guarantee, whatever its size.

How the job changes by surface

Roofline trims

We reseal trim joints with an exterior sealant.

uPVC fascias

Our work is the joints, not new fascias. If boards are damaged, we’ll tell you.

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.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Honest limits

We’d rather tell you now than do work that will not last, so these are the limits:

  • Leaks from the roof rather than a joint
  • Rotten or damaged fascia boards
  • Cracked, split or warped gutter sections

Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

Common problems we fix in Radnage

Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away over time.

Common reasons people contact us are:

  • Dripping gutter ends
  • Internal damp traced to a gutter joint
  • Fascia boards with gaps between them

What we do, step by step

When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work starts. Most jobs take anything from an hour or two to a few hours. Somewhere like Radnage needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we agree which joints need sealing.
  2. We clean out each joint.
  3. We make sure everything is dry.
  4. The sealant is applied and finished.
  5. The joints are checked once sealed.

Preparing for the visit

Your questions about gutter sealing in Radnage

Do you cover Radnage for gutter sealing?

Yes. We work across London and the South East, and Radnage is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.

Will you come out to Radnage?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you remove the old sealant?

Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.

Do the sealants smell?

Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

Do you clean gutters?

We clear what’s around the joints we work on. Full gutter cleaning is a separate job.

Do you seal gaps in fascias and soffits?

Yes. Open joints along uPVC fascias and soffits can be sealed in a colour to suit.

Radnage buildings and the weather

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. With historic houses such as West Wycombe Park House (about 3.2 miles south-east) nearby, there’s older building stock in the area around Radnage 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.

If you live in an older home near Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move. Letting a property close to Saunderton station? Then leaking gutter joints on a rental are best caught before they stain the walls.

For landlords and businesses

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.

Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we’re fully insured for the work.

Keeping the joints in good condition

A little care helps the new joints last. We recommend:

  • Get a dropping gutter looked at quickly
  • Check the gutters during heavy rain
  • Rest ladders on the wall, not the gutter
  • Sort out a dripping joint early

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.
