Gutter sealing in Lissenden Gardens

Gutter sealing in Lissenden Gardens, done properly

We work across Lissenden Gardens on leaking gutter joints and roofline trims. Single-storey and low gutters are simple to reach and if it’s higher up, let us know and we will confirm what access is needed. If you are dealing with water running down the wall below the gutter and fascia boards with gaps between them, we can help, whatever the surface.

Outside work in London starts with access: side passages, upper floors and where to park. In Lissenden Gardens, joints up high may need ladders or other access, which is worth talking through when you book.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

FAQs for Lissenden Gardens

Is parking an issue for gutter sealing in Lissenden Gardens?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.

Can you help a landlord with a rental near Gospel Oak station?

Yes, we work for landlords and agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.

What do you need from me for a quote?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.

Can you fit new guttering?

No. We seal leaking joints and trims. A gutter installer or roofer deals with replacement.

Can you match the sealant colour?

We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.

Are you insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

What sealant do you use?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.

Are you an approved applicator?

Yes. We’re an ARBOMaster approved applicator.

What affects the cost of gutter sealing

Every job gets its own quote. These are the things that affect it:

  • Whether old sealant or filler has to be cut out
  • Which sealant suits the joint
  • How easy the joints are to reach
  • Any mould that needs treating

Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

What to tell us for a quote

Photos help, but a description is a good start. Try to tell us:

  • Whether it’s a home or a business
  • The rough size of the job
  • Pictures of the joints, sent by email
  • The problem you’ve noticed

Want a quote for gutter sealing? Please ring 0345 464 0079 or drop us an email and tell us about the job. You will know what we plan to do, and what it will cost, before any work begins.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

What gutter sealing looks like in Lissenden Gardens

With historic houses such as Keats House (about 0.8 miles west) nearby, there’s older building stock in the area around Lissenden Gardens as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.

Letting a property close to Gospel Oak station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. As a London address, Lissenden Gardens can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

What we can’t put right

We will always be straight with you, so here’s what sealant cannot fix:

  • Blocked downpipes
  • A gutter length that has split
  • Brackets that have snapped or loosened

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

Where we work in Lissenden Gardens

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

How to look after the new joints

Joint life depends on how it’s used and looked after. We suggest:

  • Make sure downpipes are not blocked
  • Check fascia and soffit joints for gaps
  • Keep ladders off the guttering
  • Clean out the gutters once or twice a year

Have a look at the gutter during a downpour now and then. Drips are easiest to spot while it’s raining.

A drip from a gutter joint will not stop on its own. Water keeps hitting the same part of the wall and that can cause damp inside.

Do you need gutter sealing in Lissenden Gardens?

Overflowing gutters can look like leaking joints. A blocked downpipe makes water back up, which is why we look before we seal.

The problems people generally mention when they call are:

  • Water dripping where gutter sections meet
  • Gaps along fascia and soffit joints
  • Internal damp traced to a gutter joint
  • Failed sealant on a garage door frame

Managing a site like Parliament Hill School? Then its movement joints, gutters and trims need looking after like any other building’s.

How to choose a mastic man

Surface by surface

Soffit joints

Soffits sit under the eaves, where joints can open up. They’re sealed to tidy the line.

Garage door frames

Garage door frames let rain in when their sealant fails. We cut it out and reseal.

What happens on the day

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 London area like Lissenden Gardens, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  1. We find where the water is coming from and check the gutter is sound.
  2. We remove the old sealant and clean the joint.
  3. The joint is dried before sealing.
  4. A gutter sealant is applied to the joint.
