Questions from Britwell

Do you cover smaller places like Britwell?

Yes. Britwell is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you cover Britwell for gutter sealing?

Yes. We work across London and the South East, and Britwell is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.

I’m a tenant. Can you help?

We can work for tenants, landlords or agents. Just make sure your landlord agrees.

What does gutter sealing cost?

We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

Is gutter cleaning part of the job?

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

Do you replace gutters or fascias?

That is not something we do. We seal joints; replacing gutters and fascias needs a gutter or roofline installer.

Can you match the sealant colour?

We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.

Do the sealants smell?

There can be a smell while the sealant cures, but it fades. Ventilation helps.

Gutter sealing in Britwell

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. We work on gutter joints, uPVC fascias and garage door frames, and common reasons people get in touch are old sealant on roofline trims that has split and wet patches on the wall under a gutter joint.

Homes around Britwell range from older cottages to newer houses, with walls and rooflines of every type. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.

A 12-month guarantee comes as standard.

How to look after the new joints

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

  • Check fascia and soffit joints for gaps
  • Keep ladders off the guttering
  • Watch the wall under the gutters for staining
  • Keep downpipes clear

Give the sealant the cure time we tell you and avoid disturbing it.

The sooner a gutter leak is sealed, the less water reaches the wall. We’ll let you know if the gutter needs more than sealant.

Signs you need gutter sealing in Britwell

Gutter joints rely on seals that age. Sun and cold make the gutter expand and contract and that movement opens up tired joints.

Signs it’s time to call us include:

  • Drips from gutter joints and end caps
  • Wet patches on the wall under a gutter joint
  • Damp on an inside wall under a dripping gutter
  • Rain getting in around a garage door

Homes close to Church of St Mary include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Questions to ask before you book

  • Are they insured?
  • Whether you can choose the colour
  • Is the old sealant removed completely?
  • What the cure time is

Walls and rooflines in Britwell

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. Historic houses like Dorney Court (about 2.9 miles south-west) are a reminder that the area around Britwell has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.

If you let a flat or house near Burnham station, leaking gutter joints on a rental are best caught before they stain the walls. For site and facilities teams at buildings such as Claycots School, larger buildings have long runs of movement joint that eventually need resealing.

What we do, step by step

At the end, we look at the finished work together. The work normally takes anything from an hour or two to a few hours, depending on the amount of work. For a job in Britwell, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. First, we find the drip and check the gutter is not cracked 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

  • Mention if the joints have been sealed before
  • Plan for the work area to be out of bounds to pets and children
  • Where the joints are inside, avoid wetting them before we arrive

Advice

What the job involves on each surface

uPVC fascias

Joints between fascia boards can open over time. They’re sealed tidily with a matching sealant where possible.

Gutter joints

When a joint drips, the gutter is often still sound. Resealing is generally enough.

Can I do it myself?

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
