External mastic for Buckskin homes and businesses

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. 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.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

External mastic in Buckskin

External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on concrete & block, joints between brick and frames and render & cladding joints, and common reasons people get in touch are rain getting behind render or cladding at a joint and panel joints letting water in.

Homes around Buckskin range from older cottages to newer houses, with walls and rooflines of every type. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.

Whatever the size of the job, it’s backed by our 12-month guarantee.

Buckskin buildings and the weather

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as The Vyne (about 3.8 miles north-east) nearby, there’s older building stock in the area around Buckskin as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.

For landlords with property near Basingstoke station, split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Chiltern Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

We cover 683 towns and villages across Hampshire, from the larger towns to small villages. Reading is on our list too, about 15 miles from Buckskin.

How the visit works

Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. A visit to Buckskin is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. First, the joints are inspected and the access agreed.
  2. We cut out the old mastic and rake out anything in the joint.
  3. The faces are brushed clean and primed where the product requires it.
  4. Backing rod sized to the joint goes in to set the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about any water getting in
  • Mention any sign-in or site rules at work premises

Landlord and commercial work in Buckskin

For anyone letting property in or around Buckskin, several properties can be quoted together. Just tell us the addresses and what each one needs.

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • Adding movement joints to masonry that has none
  • Cracked brickwork or render that needs a builder or plasterer
  • Failed render or damaged cladding panels

If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.

What we seal

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

How to look after the new joints

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

  • Get split or bare joints resealed while the damage is small
  • Keep movement joints as flexible joints, not mortar
  • Clear growth from the base of walls and joints
  • Avoid pressure-washing directly into sealant joints

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.

A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.

When to call us in Buckskin

Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.

Look out for these signs:

  • Gaps where render, brick and frames meet
  • Failed sealant between panels on a façade
  • Brick movement joints where the sealant has split
  • Sealant that has lost its bond to the brick or render

In the older streets around Church of St Thomas A Becket, older walls, gutters and the joints where extensions meet them need a flexible sealant.

10 questions to ask before you book

How the job changes by surface

Brickwork movement joints

Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.

Joints between dissimilar materials

Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.

Buckskin: your questions answered

I let a flat near Basingstoke station. Can you help?

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

Can you do external mastic in Buckskin?

Yes, Buckskin is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear quote.

Which products 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.

Should I try DIY first?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

What should I tell you?

Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or email us.

Can you seal over the old sealant?

No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.

How long will you be here?

It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the building. We will give you a better idea when we quote.

Do I need to be at home?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
