Mastic sealing for Chidham sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Doing it in-house

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Mastic sealing for commercial buildings in Chidham

Managing agents and housing associations typically need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. We work on communal entrances and stairwells, shopfronts below residential blocks and balcony and threshold joints, and the usual reasons a site gets in touch are open joints in brickwork or panels and estate-wide sealant that is simply worn out. A specialist sealant contractor works differently from a general builder: in Chidham, that means joint design, primers and backing rod as standard.

For owners with a single building near Chidham, we plan to finish in one visit where possible. Send photos of the frames and joints and we will give a fixed quote.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What affects the price in Chidham

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

  • Quantities, in metres or numbers
  • Joint width, depth and condition
  • Removal of failed or old sealant
  • Site requirements such as inductions and permits

Every site prices differently: 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

Diagnosis starts before we arrive. Tell us:

  • Any specification or named product
  • When you need the work done
  • Anything awkward about access or site hours
  • Whether an asbestos survey exists

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or email drawings and photos.

Blocks and managed buildings in Chidham

With the shore within about 1 mile, Chidham counts as a coastal location. On buildings near the shore, the side facing the weather usually needs its mastic renewed first, so it’s worth inspecting those sides more often. Chidham has four care or nursing homes no more than 2 miles away. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents.

Student accommodation around universities such as University of Chichester, 4.5 miles east of Chidham, is usually managed block by block, which suits a planned mastic programme. Landlords with units on estates such as Southfield Industrial Park., 1 mile to the east of Chidham, can bring frame, door and external mastic across several units into one programme.

When to call us in Chidham

We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.

Look out for the following:

  • Failed external movement joints
  • Patchy repairs in mismatched sealant
  • Window mastic that has split and shrunk
  • Worn sealant at communal door frames

Churches, halls and community buildings such as The Parish Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Questions to ask before you appoint anyone

Questions about Chidham

Can you work in a care home near Chidham with residents in?

Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.

Will you take on work at estates like Southfield Industrial Park., close to Chidham?

Yes. We cover Chidham and the area around it, including industrial estates, business parks and retail parks such as Southfield Industrial Park.. A few photographs and the unit address let us price the work.

Do you do block-wide mastic programmes?

Block-wide and estate programmes are common. The quote can be split however suits your budgeting.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Do you supply RAMS and insurance details?

Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

On site: what to expect

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For work around Chidham, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  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. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

What we need from you

  • Let building users know which areas are affected
  • Explain the parking and delivery arrangements
  • Share the asbestos register for older buildings

Getting a fixed quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Aftercare for building managers

To get the most from the new sealant:

  • Log resealing dates block by block
  • Check sealant joints during planned building inspections
  • Ask residents or tenants to report leaks and draughts early
  • Have the asbestos survey to hand for older buildings

Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.

Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.
