How it works

On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on the building. In central Ashford, parking can be tight, so tell us about driveways, permits or nearby car parks. Let us know about stairs, lifts or shared entrances too.

  1. First we look over the joints with you, agree which to renew and talk through access.
  2. Old sealant and any debris are cut and raked out.
  3. We clean both faces of the joint and prime them where the product calls for it.
  4. We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
  5. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

Before we arrive

  • For business premises, tell us about site rules or sign-in
  • Tell us about any water getting in
  • Tell us if parking is tricky

Advice

How we handle external mastic in Ashford

We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. If you are dealing with old sealant gone brittle and cracked and failed sealant between panels on a façade, we can put it right.

A place the size of Ashford has buildings of every age, from older brick terraces to modern blocks with rendered or clad walls. Newer buildings rely on sealed movement joints, while older ones need their gutters, fascias and trims kept tight.

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

Ashford questions

Is Ashford in your area for external mastic?

Yes, Ashford is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.

I let a flat near Ashford International station. Can you help?

Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

How long should I leave it?

It depends on the product and the conditions. We tell you how long to leave it before we go.

What do you put in the joint?

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

What should I tell you?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Can new sealant go over the old?

No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Can you quote for more than one area?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

When something else is needed

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Failed render or damaged cladding panels
  • Cutting new joints into brickwork, which is building work rather than sealant work

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

Joints and surfaces we work on

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

Landlord and commercial work in Ashford

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.

How to look after the new joints

So the new joints stay in good condition:

  • Clear growth from the base of walls and joints
  • Point out the joints to other trades
  • Ask before painting over external sealant
  • Never let anyone fill a movement joint with mortar

Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.

Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.

Should I try it myself first?

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.

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.

How the job changes by surface

Brickwork movement joints

Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.

Joints between dissimilar materials

Different materials may need different primers. We prepare both faces so the sealant bonds properly.

Why act early in Ashford

Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In a busy place like Ashford, a failed joint in a flat or office can send water into the space below, where it’s often found late and is bigger to put right.

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What external mastic looks like in Ashford

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Godinton House (about 2 miles north-west) are a reminder that the area around Ashford has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.

For site and facilities teams at buildings such as Chilmington Green Primary School, its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Ashford International station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Christ Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
