Need external mastic in Ditton?

Can I do it myself?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

External mastic for homes and businesses in Ditton

Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the joint doesn’t stand out. If you’re dealing with joints pointed up with cement by mistake and gaps where render, brick and frames meet, we can put it right, on brickwork movement joints, render & cladding joints and concrete & block alike.

Around Ditton, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in.

All our work comes with our one-year guarantee, wherever you are in Slough.

What affects the quote in Ditton

Every job gets its own quote. These are the things that affect it:

  • The type of sealant required
  • Whether old sealant or filler has to be cut out
  • Whether there’s mould to deal with
  • The number and length of the joints

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What we need to know

Before you ask for a quote, have a think about:

  • What the problem is, such as mould, gaps, leaks or cracking
  • How many joints, rooms or windows are involved
  • Where the job is, and your postcode
  • A few photos by email, if you can

Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or send us an email and describe the job.

Keeping the joints in good condition

How long the joints last depends on use and care. Here’s what we suggest:

  • Act on the first splits you see
  • Keep movement joints as flexible joints, not mortar
  • Do not let climbing plants root in the sealant
  • Keep high-pressure jets off the joints

Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.

Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick.

Surface by surface

Cladding and façade panels

Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.

Joints between dissimilar materials

Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.

What we do, step by step

The work is kept neat and contained to the joints we are treating, so you can carry on as normal. The job generally takes a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. In a small place like Ditton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each joint is checked and the colour of the new sealant agreed.
  2. Failed sealant is removed back to clean, sound faces.
  3. Backing rod goes in so the sealant can stretch between the two faces.
  4. We prime the faces where required.
  5. We gun in low-modulus sealant and tool it neatly.

How to prepare

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention if the joints have been sealed before
  • Tell us about any water getting in

How to get a quote

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, phone 0345 464 0079 or drop us an email.

External mastic in Ditton: local notes

The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Frogmore House (about 1.7 miles south-west) nearby, there’s older building stock in the area around Ditton as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.

For landlords with property near Datchet station, outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to St Francis Assisi include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

Honest limits

We’ll always be straight with you, so here’s what sealant cannot fix:

  • Walls that need new movement joints cut into them
  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Structural movement, which needs a surveyor or engineer

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

FAQs for Ditton

Can you do external mastic in Ditton?

Yes. Our work covers London and the South East, and Ditton is part of that. Just call 0345 464 0079 or email us with a few details of the job.

Is Ditton within the area you cover?

Yes. Ditton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you have insurance?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Can you do several jobs on one visit?

Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.

Will it make a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

How often do external joints need resealing?

There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.

I rent my home. Can I book you?

We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.

When to call us in Ditton

Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.

People normally contact us after spotting something like this:

  • Failed sealant between panels on a façade
  • Joints with sealant missing in places
  • Moss and dirt in joints with no sealant left
  • Cracked joints where brick meets render or frames

Managing a site like Castleview Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

What your quote should include

  • How long to leave it before use
  • Whether they’re fully insured
  • What the quote includes, VAT included or not
  • How the joint is cleaned and prepared
