About our gutter sealing in Upper Common

A lot of gutter leaks come down to one tired joint. The joint is cleaned, dried and resealed with a sealant made for guttering. If the gutter itself has failed, we say so. We work on garage door frames, gutter end caps and uPVC fascias, and common reasons people get in touch are quick sealant fixes on gutters that didn’t last and old sealant on roofline trims that has split.

Outside joints can only be sealed when they’re dry, so work in Upper Common is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.

You get a one-year guarantee, the same in Upper Common as everywhere else we work.

Common problems we fix in Upper Common

A sealant applied to a damp or dirty joint won’t bond. Rushed repairs often don’t last long for this reason.

These are the problems we’re asked about most:

  • Trim joints where the sealant has failed
  • Earlier gutter repairs that have peeled off
  • Damp patches inside below a leaking gutter
  • Fascia boards with gaps between them

10 questions to ask before you book

What happens if it’s left?

New gutters cost far more than a few resealed joints. If the gutter is sound and the drip is a joint a reseal is all it needs. If it has failed, we will tell you. Older cottages and farmhouses around Upper Common can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

The process

We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from an hour or two to a few hours. In a small place like Upper Common, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. We dry the joint so the new sealant can bond.
  4. We seal the joint with a sealant made for gutters.
  5. The gutter is checked and debris around the joints cleared.

Before we arrive

  • Tell us if parking is tricky
  • Clear the area around the work
  • Keep children and pets away from the work area

How to get a quote

Advice

Gutter sealing in Upper Common: local notes

Rainfall in the South East is lower than in much 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 Hall Place (about 3.9 miles south-east) nearby, there’s older building stock in the area around Upper Common as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.

If you live in an older home near Church of St. Martin, older walls, gutters and the joints where extensions meet them need a flexible sealant.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Work for landlords, hotels and businesses

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

Upper Common: your questions answered

Will you come out to Upper Common?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you cover Upper Common for gutter sealing?

Yes, Upper Common is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.

Do you offer different sealant colours?

Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.

Is it OK to seal over old sealant?

No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

Will the old sealant be removed?

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

Do you have insurance?

Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.

Can a leaking gutter joint be sealed?

In most cases, yes. If the gutter is sagging or cracked, sealing won’t last and we will say so.

Will you clear out my gutters?

We clear debris around the joints we’re sealing. A full clean of the gutters is not part of it.
