Gutter sealing in North Lee

Walls and rooflines in North Lee

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

For site and facilities teams at buildings such as Stoke Mandeville Combined School, its movement joints, gutters and trims need looking after like any other building’s. In the older streets around Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.

About our gutter sealing in North Lee

Gutter and fascia replacement isn’t our trade, and nor is roofing. What sealant does is close joints and it cannot mend broken brackets, split sections or blocked downpipes. We are often asked to deal with rain getting in around a garage door and streaks down the brickwork from a leaking joint, across soffit joints, roofline trims and gutter joints.

Somewhere as small as North Lee, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Different surfaces, different methods

Gutter end caps

We seal end caps from the inside where we can reach, after cleaning and drying.

Roofline trims

Trim joints are cut out and resealed suited to the material.

Can I do it myself?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

What we are called out for in North Lee

Gutter joints depend on seals that wear out. Temperature changes make gutters move, and old seals crack or slip.

People generally contact us after spotting one of these:

  • Dripping gutter ends
  • Wet patches on the wall under a gutter joint
  • Cracked sealant along roofline trims
  • Failed sealant on a garage door frame

Rented homes near Stoke Mandeville station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Our hiring checklist

Work for landlords, hotels and businesses

In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

If you manage several properties in or around North Lee, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.

What affects the cost of gutter sealing

You’ll get a clear quote before any work starts. It takes into account:

  • Mould in or behind the old joints
  • Working hours on commercial sites
  • Whether the work is at height
  • The product the joint needs

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What we need to know

There’s no need for technical detail. It helps if you can tell us:

  • Whether it has been sealed before
  • Roughly how big the job is
  • Pictures of the joints, sent by email
  • The type of property

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you are ready, phone 0345 464 0079 or send us an email.

What sealant work can’t fix

Some problems need a builder, plumber or other trade rather than us:

  • Rotten or damaged fascia boards
  • Leaks from the roof rather than a joint
  • Blocked downpipes

If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before booking.

Where we work in North Lee

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

What we do, step by step

Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a few hours. In a small place like North Lee, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at where the water is coming from and check the gutter is not broken or sagging.
  2. Old sealant and dirt are removed from the joint.
  3. The joint is dried, because sealant will not bond to a wet surface.
  4. An exterior or gutter sealant is applied to the joint.
  5. We check the run and clear any debris we find while we’re there.

Before we arrive

  • Tell us about access, such as stairs, a lift or high-level joints
  • Clear items away from the joints we are working on
  • Tell us about any previous sealing or DIY attempts

North Lee questions

Can you help a landlord with a rental near Stoke Mandeville station?

Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.

Will you come out to North Lee?

Yes, North Lee is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Will sealing fix a sagging gutter?

Sealing a sagging joint won’t last. The gutter needs refixing by a gutter installer.

Can you do several jobs on one visit?

Yes. Tell us about everything you’d like done.

Can you match the sealant colour?

Most of the time, yes. We will tell you which colours the right product comes in and agree one before any work starts.

Is it possible to stop a gutter joint dripping with sealant?

Yes, as long as the gutter itself is in good order. The joint is cleaned and dried first so the seal holds.

Does someone need to be in?

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

When is the sealant fully cured?

Different products cure at different speeds, so please follow the time we give you.
