Questions we are asked in Chiltington

Is hospital work, at somewhere like Lewes Victoria Hospital, something you do?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Chiltington too small for you to travel to?

No. Places such as Chiltington are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or email us. Include photographs or drawings if you have them.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

What hours do you work?

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.

About our facade sealing in Chiltington

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Coping and flashing joints are included where sealant is the specified fix. We work on stone and brick facade joints, coping and flashing joints and perimeter joints where frames meet the structure, and the failures we’re asked to look at most are perimeter joints where frames meet the structure and draughts around frames and panels. Whether you call it commercial sealant work, mastic application or joint sealing, in Chiltington it comes down to the same thing: the right product in a properly prepared joint.

For a site near Chiltington, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we are called out for in Chiltington

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

If one of these sounds familiar, it’s time for a closer look:

  • Draughts around frames and panels
  • Facade joints cracked through the middle
  • Unsightly perimeter sealant on a visible elevation
  • Failed seals around shopfront and entrance frames

Building work at universities like University of Sussex, 2.7 miles north of Chiltington, is often timed for the summer, mastic included.

Before you book anyone

  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Who will actually carry out the work
  • What site paperwork they can supply

Our contractor checklist

Sites and facades in and around Chiltington

Rainfall across the South East, Chiltington included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Chiltington lies roughly 40 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.

School extensions, at buildings such as Chailey School, typically run to the summer holidays, mastic included. Historic houses such as Anne of Cleves House, 3.7 miles south of Chiltington, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Chiltington is about 3 miles north-west of Lewes, in East Sussex. We cover commercial sites throughout Chiltington, whether it’s a single job or part of a planned programme. Chiltington is one of 308 places in East Sussex on our list. Brighton is covered too, some 7 miles away.

Our process

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If others near Chiltington need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Tell staff and tenants when we’ll be in
  • Share your working hours and any access restrictions
  • Have the specification and drawings to hand

Advice

Owners, agents and contractors

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Cost factors for facade joints

Quotes vary with the job. Expect it to depend on:

  • Backing rod, priming and other preparation
  • Travel to remote or island sites
  • How accessible the joints are
  • How much there is to seal

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What we need to price the job

However big the job, the same details help:

  • The postcode of the building
  • Anything awkward about access or site hours
  • A wide shot and a close-up of the area
  • Whether an asbestos survey exists

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or ring 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Why deal with it now?

Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Converted and older buildings near places like Chiltington tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What you get with us

  • Colour agreed before work starts
  • One phone line for London, the South East and Scotland

Different surfaces, different methods

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them.

Render and coated surfaces

Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.
