External & façade joints in Newington, Kent

External mastic near Newington

Looking after it afterwards

Looking after new joints is easy:

  • Avoid pressure-washing directly into sealant joints
  • Keep water from gutters off the wall
  • Act on the first splits you see
  • Never let anyone fill a movement joint with mortar

Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.

A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.

How we handle external mastic in Newington

On houses, flats and commercial buildings across Newington, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. If you have gaps where render, brick and frames meet and old sealant gone brittle and cracked, we can put it right, whatever the surface.

Outbuildings, garages and conservatories around homes in places like Newington add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.

You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Walls and rooflines in Newington

Newington is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Quex Park (about 3.4 miles west) are a reminder that the area around Newington 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.

Rented homes near Ramsgate station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as St Christopher's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Newington is about 1 mile north-west of Ramsgate, in Kent. From the centre of Newington to the outskirts, we cover external mastic for every kind of property, from flats and houses to offices and hotels.

Quotes for external mastic in Newington

Your quote is based on your job. We look at:

  • The number of rooms or windows
  • Which sealant suits the joint
  • Whether the work is at height
  • The number and length of the joints

What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear price before work begins.

Asking for a quote

When you call or email, it’s useful to know:

  • Roughly how big the job is
  • Any previous sealing or DIY work
  • What the problem is, such as mould, gaps, leaks or cracking
  • If it’s domestic, commercial or a hotel

If you are in Newington and need external mastic, phone 0345 464 0079 or drop us an email. Tell us what the problem is and where, and you’ll get a clear quote before we start.

How the visit works

At the end, we look at the finished work together. The visit itself normally takes a few hours to a few days, depending on the length of joint and the access, depending on how much there is to do. For a job in Newington, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We start by walking round the building and agreeing the joints and the access.
  2. Every bit of old sealant and any mortar or debris is cut out.
  3. Joint faces are cleaned back and primed if the sealant needs it.
  4. We fit closed-cell backing rod to control the depth.
  5. We apply the sealant, tool it and check the whole run.

How to prepare

  • Move anything stored near the joints
  • Mention any parking rules near the property
  • Plan for the work area to be out of bounds to pets and children

When to call us in Newington

A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.

Look out for these signs:

  • Rain getting behind render or cladding at a joint
  • Plants rooting in failed movement joints
  • Movement joints with cracked, split or missing sealant
  • Gaps where render, brick and frames meet

If you look after a building such as Ramsgate Arts Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What to look for in a quote

  • Are they insured?
  • Is the old sealant removed completely?
  • How much experience the applicator has
  • How hidden problems are handled

How to choose a mastic man

DIY sealant or a professional job?

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

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What sealant work can’t fix

We will not take on work that will not last, so here’s what sealant cannot put right:

  • Adding movement joints to masonry that has none
  • Cracking across the wall rather than at a joint
  • Damp from another source, such as a leaking gutter or a bridged damp-proof course

Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

What we seal

  • Façade panels
  • Render & cladding joints
  • Concrete & block
  • Joints between brick and frames
  • Copings & trims
  • Brickwork movement joints

Why deal with it now?

The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the problem grows beyond the joint itself. Around Newington, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Why choose Mr Mastic in Newington

  • Old sealant always removed completely
  • Tidy, careful work
  • Experience in homes, commercial sites and hotels
  • Full insurance on every job

Your questions about external mastic in Newington

Will you come out to Newington?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Does the coastal weather in Newington affect outside sealant?

Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.

How long will you be here?

That depends on how much there is to do, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We will tell you when we quote.

Will the new joint stand out?

Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it doesn’t stand out.

What sealant do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Do you work for letting agents?

Yes, we do. We work in homes, commercial premises and hotels, and we are fully insured.

Why do you put foam in the joint first?

Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.

Is it OK to seal over old sealant?

No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
