FAQs for Burghclere

Do you work for landlords with property near Newbury station?

Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.

Is Burghclere in your area for external mastic?

Yes. We work across London and the South East, and Burghclere is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.

What information do you need?

A short description and the location, plus pictures if you have them. We will ask anything else we need to know.

Is it worth trying it myself?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Can a movement joint be filled with mortar?

No. A mortar-filled joint can’t move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.

Do you work at height?

It depends on the building. Where joints can be reached safely, we will do them. Give us some details and we’ll confirm the access.

How long will you be here?

That depends on how much there is to do, but most jobs take a few hours to a few days, depending on the length of joint and the access. We will give you a better idea when we quote.

Can you work on commercial sites?

Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.

External mastic in Burghclere

Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. If you have rain getting behind render or cladding at a joint and failed seals between different materials, we can help, on façade panels, joints between brick and frames and copings & trims alike.

Older homes in small places like Burghclere may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.

We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

Honest limits

A few problems are outside what sealant work can do:

  • Rising or penetrating damp from elsewhere in the wall
  • Cracked brickwork or render that needs a builder or plasterer
  • Structural movement, which needs a surveyor or engineer

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

What we seal

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

Should I try it myself first?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

How the job changes by surface

Copings and trims

Copings expand and contract through the day, so a flexible sealant suits them best in all weathers.

Concrete and blockwork

The face of concrete or block is often dusty, so preparation is key. A primer goes on where the product requires one.

Landlord and commercial work in Burghclere

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

How it works

The work is kept neat and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. In a small place like Burghclere, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at every joint and agree a colour to suit the wall.
  2. We take out the old sealant until the faces are sound.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. We prime the faces where required.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Leave it or put it right?

A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. In a small place like Burghclere, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

Why us?

  • We are fully insured
  • Approved under the ARBOMaster scheme
  • Experience in homes, commercial sites and hotels
  • Anti-fungal silicone where joints get wet

Outside joints around Burghclere

Historic houses like Highclere Castle (about 1.9 miles south-west) are a reminder that the area around Burghclere has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

In the older streets around Church of the Ascension, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like Burghclere Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Newbury station, split movement joints are easy to miss on a rental until damp shows inside.

Keeping the joints in good condition

Aftercare is simple, and it makes a real difference:

  • Act on the first splits you see
  • Check external joints each spring
  • Make sure movement joints are not pointed over
  • Keep water from gutters off the wall

Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.

Once a joint can’t move, the wall finds another way, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
