Surface by surface

Copings and trims

Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.

Joints between dissimilar materials

Wherever two materials meet, they move differently. A flexible sealant bridges the two so neither cracks the other.

How we handle external mastic in Durford Wood

For buildings in Durford Wood, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Common call-outs are for joints pointed up with cement by mistake and moss and dirt in joints with no sealant left, on joints between brick and frames, brickwork movement joints and façade panels.

External sealant needs dry, clean surfaces, so work around Durford Wood is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.

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

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.

Walls and rooflines in Durford Wood

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Rented homes near Liss station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Managing a site like Liss Infant School? Then larger buildings have long runs of movement joint that eventually need resealing.

Honest limits

Sealant is not the answer to every problem, and we’ll tell you before we start. Sealant will not put right:

  • Rising or penetrating damp from elsewhere in the wall
  • Failed render or damaged cladding panels
  • Cracking across the wall rather than at a joint

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.

Where we work in Durford Wood

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

How to look after the new joints

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Make sure movement joints are not pointed over
  • Check the sealant is paintable before painting near it
  • Do not let climbing plants root in the sealant
  • Show decorators and builders where the movement joints are

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, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

What happens on the day

When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Durford Wood, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. The joint faces are cleaned and primed where the sealant needs it.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Getting ready for the visit

  • On commercial sites, let us know about site rules
  • Try not to wet indoor joints just before the visit
  • Move anything stored near the joints

Advice

Do you need external mastic in Durford Wood?

Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.

If you can see any of these, it’s time to have the joints looked at:

  • Rigid filler in a joint that should flex
  • Failed sealant between panels on a façade
  • Moss and dirt in joints with no sealant left
  • Movement joints with cracked, split or missing sealant

Homes close to Church of St Mary include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Questions to ask before you book

  • What product goes in the joint
  • What happens if the job turns out different
  • Are they insured?
  • How much experience the applicator has

10 questions to ask before you book

Common questions in Durford Wood

Do you cover smaller places like Durford Wood?

Yes. Durford Wood is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you cover Durford Wood for external mastic?

Yes, Durford Wood is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.

Can you do several jobs on one visit?

Yes. Several rooms, windows or areas can go on one quote.

Do you use backing rod?

That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.

Will you leave a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

Should I point up the gap in my brickwork?

No, not where the gap is a movement joint. Filling it with mortar defeats its purpose. We’ll reseal it with a flexible sealant.

What does external mastic cost?

Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or drop us an email with a short description of the job.

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. We remove it all first.
