Mastic packages on Whitehill sites

A 2-mile radius around Whitehill takes in several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Rainfall across the South East, Whitehill included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

Historic houses such as Belmont House and Gardens (2.4 miles south-west of Whitehill) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Hotels like Premier Inn Faversham Hotel (to the north-east of Whitehill) rarely close for long, so refurbishment mastic is phased floor by floor.

Whitehill is about 1 mile south-west of Faversham, in Kent. Anywhere in ME13, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Kent, 931 places are covered, including Whitehill. For work in that direction, see our London page, about 44 miles away.

How we handle facade sealing in Whitehill

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. We work on perimeter joints where frames meet the structure, window and door perimeters and cladding panel joints, and the usual reasons a site gets in touch are weathered joints at frame-to-structure perimeters and discoloured or dirty facade joints. Facilities teams, main contractors and managing agents in Whitehill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In the countryside around places like Whitehill, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Cost factors for facade joints

A fixed quote reflects the actual work. It takes account of:

  • Whether old sealant has to be cut out first
  • Induction, permit and paperwork requirements
  • Travel to remote or island sites
  • Access and working height

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

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • Whether the building will be occupied during the work
  • Any specification or named product
  • Drawings or a marked-up plan, if available
  • Whether an asbestos survey exists

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Doing it in-house

Paperwork matters too. 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: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Do you need facade sealing in Whitehill?

When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

Look out for the following:

  • New sealant peeling off old mastic
  • Perimeter joints where frames meet the structure
  • Facade joints cracked through the middle
  • Air leaks through failed facade joints

When a school such as Ospringe Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • Do they follow the manufacturer’s priming guidance?
  • Their plan for phasing and protecting the area
  • Is the sealant right for the movement and the substrate?

How to choose a sealant contractor

Aftercare for building managers

Regular inspection catches problems early. In particular:

  • Keep sills, gutters and drainage paths clear
  • Combine resealing with other works that need access
  • Check the asbestos register before old mastic is disturbed
  • Insist on a full cut-out when joints are renewed

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

Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones inside the building.

Your questions answered

Can the mastic package for our job in Whitehill follow the site programme?

Yes, we work to the programme and the sequence the site sets. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is a smaller place like Whitehill outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is it okay to overlay old mastic?

No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Do we need an asbestos check before resealing?

In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first. We don’t remove asbestos-containing materials.

How the job changes by surface

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed with a product suited to glazing perimeters.

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone.

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Whitehill are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Before we start on site

  • Have the specification and drawings to hand
  • For older buildings, check the asbestos register before work
  • Tell us what induction or permit system the site runs
