Gutter sealing in Farthing Street

About our gutter sealing in Farthing Street

We seal leaking gutter joints, end caps, fascia and soffit joints plus roofline trims and garage door frames. It’s all about the joints, not replacing the gutter. We’re often asked to deal with drips from gutter joints and end caps and wet patches on the wall under a gutter joint, on garage door frames, roofline trims and uPVC fascias.

In London terraces and converted houses, gutters and walls are often shared with the house next door, so a leaking gutter joint or failed wall joint can affect more than one home. For a flat in Farthing Street, check the lease for who looks after the outside.

Whatever the size of the job, it’s backed by our one-year guarantee in Farthing Street and across Greater London.

Quotes for gutter sealing in Farthing Street

For a quick quote, just ask. What matters most is:

  • Whether old sealant or filler has to be cut out
  • The type of sealant required
  • How many areas need sealing
  • When we can work, for business premises

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What we need to know

There’s no need for technical detail. Just tell us:

  • Any access issues, like height or stairs
  • Photos by email, if that’s easy
  • What the problem is, such as mould, gaps, leaks or cracking
  • The type of property

There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or drop us an email.

What we can’t put right

Sealant isn’t the answer to every problem, and we will tell you before work begins. Sealant won’t put right:

  • Water backing up from a blocked pipe
  • Rotten or damaged fascia boards
  • Leaks from the roof rather than a joint

Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.

What we seal

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

Different surfaces, different methods

Roofline trims

Roofline trims rely on sealant at their joints. When it splits, water can get behind.

Gutter joints

Gutter joints move and sit in water. A gutter sealant made for the job holds best.

Signs you need gutter sealing in Farthing Street

Sealant on fascias and trims weathers like any outdoor joint. It goes hard, cracks and pulls away over time.

Keep an eye out for any of the following:

  • Drips from gutter joints and end caps
  • Quick sealant fixes on gutters that didn’t last
  • Water running down the wall below the gutter
  • Open joints in fascias and soffits

Letting a property close to Orpington station? Then leaking gutter joints on a rental are best caught before they stain the walls.

  • Is VAT in the price?
  • Who does the work, and how experienced they are
  • When the joint can take water or movement

How to choose a mastic man

Why act early in Farthing Street

If the problem is a blocked downpipe, sealing will not help. We look at what’s really happening and tell you if something else is needed. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Farthing Street, the repair is bigger than the sealant job would have been.

A failed joint rarely gets cheaper to fix by waiting. If you are unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Why us?

  • A 12-month guarantee on all work
  • Rated 4.9 stars on Google
  • Fully insured
  • White, clear, grey or another colour, product permitting

How it works

We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from an hour or two to a few hours. In Farthing Street, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. We look at the gutters, fascias and trims and agree the joints to seal.
  2. Each joint is cleaned and any old sealant removed.
  3. The joints are dried.
  4. The sealant is applied and finished.
  5. The joints are checked once sealed.

Getting ready for the visit

  • Let us know if you’ve seen damp or leaks

Farthing Street buildings and the weather

In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking. 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.

As a London address, Farthing Street can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. In the older streets around St Mary's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Farthing Street: your questions answered

Do you work for landlords with property near Orpington station?

Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Is parking a problem for a job in Farthing Street?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

Are you insured?

Yes. We’re fully insured, and we can confirm the details when we quote.

How long should I leave it?

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

How much does gutter sealing cost in Farthing Street?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

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.

How long does the job take?

Most jobs take a few hours, depending on the number of joints and the access, including the preparation. We’ll confirm how long when we quote.

Can you work on commercial sites?

Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.

DIY versus a professional finish

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
