Facade sealing across Chithurst

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Cost factors for facade joints

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Site requirements such as inductions and permits
  • The size and state of each joint
  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.

Before you send an enquiry

Good information means a firmer quote. When you get in touch, include:

  • Your programme or deadline
  • Photos of the joints, close up and from further back
  • Access details, including height
  • Rough lengths or quantities, or drawings if you have them

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or phone 01277 525 020 or send photos by email to discuss it first.

Facade sealing for commercial buildings in Chithurst

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Site teams most often ask us about discoloured or dirty facade joints and sealant pulling away from frames or panels, across perimeter joints where frames meet the structure, stone and brick facade joints and cladding panel joints. Looking for mastic applicators who cover Chithurst? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

For a site near Chithurst, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we will quote to suit.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If others near Chithurst need work, visits can be combined. You’ll have a fixed quote before work starts.

  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. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  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. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Make sure the joints can be reached
  • Point out parking and an unloading spot
  • Send your site hours and access windows

Questions about Chithurst

Is a smaller place like Chithurst outside your area?

Not at all. Chithurst is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Does your area include sites such as Midhurst Business Centre, near Chithurst?

Yes. We cover Chithurst and the area around it, including industrial estates, business parks and retail parks such as Midhurst Business Centre. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Can you handle several sites?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Do you replace windows or glass?

No. A glazing contractor handles that. What we seal are the joints around frames and panels.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Do we need an asbestos check before resealing?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder. If asbestos is suspected, work stops until it is tested.

Why it’s worth doing now in Chithurst

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Halls, stores and units around places like Chithurst may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Why us?

  • Joints cleaned back to sound surfaces
  • Coloured sealants to suit the setting, where available
  • Colours confirmed for the specified product
  • CHAS accredited

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

For managing agents and facilities managers

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Chithurst can sit alongside others in a wider programme across West Sussex.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Facade sealing in Chithurst: the local picture

Chithurst is about 46 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. Chithurst sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.

On a healthcare site such as Midhurst Community Hospital, 2.9 miles to the east of Chithurst, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. School extensions, at buildings such as Stedham Primary School, usually run to the summer holidays, mastic included. Hotel extensions and refits, at places such as Southdowns Hotel (1.3 miles south-west of Chithurst), typically run between busy periods, so the sealing is squeezed into short windows.

Chithurst is about 6 miles east of Petersfield, in West Sussex. Our applicators travel to Chithurst for work on facade joints, handled exactly as we handle every other area.

Different surfaces, different methods

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair first.

Window and door perimeters

Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints, tooled to shed water.
