Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Keep pressure washers away from fresh sealant
  • Don’t wait for a second leak before calling
  • Keep sills, gutters and drainage paths clear
  • Confirm the survey covers external sealants in older buildings

Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade rather than sitting against the joints.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

About our facade sealing in Crossbush

Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. If you’re dealing with water coming in around window frames and patch repairs that keep failing, we can help. Looking for mastic applicators who cover Crossbush? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Around smaller places like Crossbush, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Facades, frames and programmes in Crossbush

Crossbush is within about 3 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. A 2-mile radius around Crossbush takes in several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

With historic properties like Ecclesden Manor, 3 miles to the east of Crossbush, in the area, refurbishment work often meets old masonry that needs compatible sealants. On a healthcare site such as Arundel & District Community Hospital, 1.5 miles to the north-west of Crossbush, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Hotel extensions and refits, at places such as The Camellia Hotel, under half a mile west of Crossbush, typically run between busy periods, so the sealing is squeezed into short windows.

Crossbush is about 2 miles north of Littlehampton, in West Sussex. Crossbush sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else.

Work for main contractors and building owners

Common questions from Crossbush clients

Can you work on a hospital site such as Arundel & District Community Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is The Vinery Industrial Estate, near Crossbush, within your area?

Yes. We cover Crossbush and the area around it, including industrial estates, business parks and retail parks such as The Vinery Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Is the work guaranteed?

Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.

When can you be on site?

We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Is old mastic on our building likely to contain asbestos?

In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed. Removal of asbestos isn’t something we do.

From enquiry to sign-off

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Rural sites near Crossbush may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Agree which areas must stay open
  • Make sure the joints can be reached

Why act early in Crossbush

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Halls, stores and units around places like Crossbush may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Why choose Mastic Doctor in Crossbush

  • Colour agreed before work starts
  • Failed material removed, not covered up

Quoting for work in Crossbush

Your fixed quote is built from the real scope. It allows for:

  • Location, for remote and island sites
  • Whether the work must be split into stages
  • How accessible the joints are
  • Joint width, depth and condition

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

What we need to price the job

We can often quote from photos and a few details. It helps to include:

  • The type of building and who uses it
  • Any specification or named product
  • The asbestos register, for older buildings
  • Rough lengths or quantities, or drawings if you have them

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or email a schedule or drawings with what you know.

General trades versus a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
