What happens if it’s left?

Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Converted and older buildings near places like Cross-at-Hand tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

There’s no price list, since every building and every scope is different. Call for a quote.

Signs you need mastic sealing in Cross-at-Hand

We often find joints filled solid with no backing rod so the mastic is bonded on three sides. It can’t stretch properly and it tears.

Common reasons buildings call us in:

  • Communal area joints that look neglected
  • The same joint failures repeated across a portfolio
  • Patchy repairs in mismatched sealant
  • Movement joints with sealant missing

Older buildings near Cross-at-Hand, from historic houses such as Stoneacre, 4.6 miles to the north of Cross-at-Hand, to more modest stock, need compatible products when frames are resealed.

What to look for in a quote

  • Proof of insurance
  • Their plan for phasing and protecting the area
  • Will failed sealant be removed rather than covered?
  • Will RAMS and insurance details be available?

Choosing a commercial sealant contractor

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Mastic sealing in Cross-at-Hand: the local picture

Cross-at-Hand sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Cross-at-Hand is about 35 miles from central London. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate.

If you look after a block within reach of Staplehurst station, 1.2 miles to the south of Cross-at-Hand, frame and balcony mastic can be renewed on one programme. Property owners at sites such as Barradale Farm Industrial Estate, 2.8 miles east of Cross-at-Hand, can have mastic renewed between lettings.

How a job runs

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. Rural sites near Cross-at-Hand may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

  • Make sure the joints can be reached

What affects the price in Cross-at-Hand

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

  • How accessible the joints are
  • Quantities, in metres or numbers
  • The product specified
  • How much existing material needs removing

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What we need to price the job

A good diagnosis starts with the right details. Tell us:

  • Clear photographs of the problem areas
  • The site address and postcode
  • How the joints are reached, and at what height
  • Approximate linear metres or a joint schedule

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Owners, agents and contractors

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
