Construction mastic near Morton

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

For managing agents and facilities managers

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.

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Construction mastic in Morton

The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. Sealing too early only means coming back once others have damaged it. If you are dealing with mastic snags holding up handover and a mastic package split between trades with no clear owner, we can help, on internal decorators’ caulk, cladding and panel joints and brick and block movement joints alike. Whoever orders the work in Morton, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Conversions of older rural buildings near smaller places such as Morton bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

A 12-month guarantee applies to all our work in the Isle of Wight. If an installation problem shows up, speak to us on 01277 525 020 or email us and we will arrange a return visit.

Questions we’re asked in Morton

Is a smaller place like Morton outside your area?

Not at all. Morton is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is Spithead Business Centre, near Morton, within your area?

Yes, sites like Spithead Business Centre are within our area, along with the rest of Morton. Send details of the unit and the work through our quote form for a quick quote.

Can you work while the building is occupied?

Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day.

Do you do internal caulk as well as external mastic?

External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

When to call us in Morton

Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.

Typical triggers for a call:

  • Sealant knocked or painted over by other trades
  • Perimeter gaps outside the sealant’s range
  • Different trades sealing to different standards
  • Window and door perimeters that won’t pass inspection

Extensions at sites like Arthur Webster Memorial Hospital for Children (3 miles south-west of Morton) typically sit beside working departments, and the mastic follows strict access rules.

Comparing quotes

  • Do they follow the manufacturer’s priming guidance?
  • Their plan for phasing and protecting the area
  • Will CSCS-carded applicators be on site?
  • How the existing material will be dealt with

Choosing a commercial sealant contractor

Honest limits

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Approving fire stopping as compliant
  • Joints damaged after sign-off by following trades

If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think.

What we seal

  • Brick and block movement joints
  • Window and door perimeters
  • Floor and skirting junctions
  • Internal decorators’ caulk
  • Sanitary and kitchen joints
  • Cladding and panel joints

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Ask for joint and product checks before the package is urgent
  • Don’t schedule sealing before decorators and flooring are done
  • Plan external elevations with the weather in mind
  • Brief following trades on areas that have been sealed

Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.

Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short, and avoids a rush.

Doing it in-house

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. If others near Morton need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First we take quantities off the drawings and read through the specification.
  2. You receive a fixed quote listing scope, products and phasing.
  3. You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
  4. Areas are sealed plot by plot or floor by floor as the trades hand them over.
  5. Each joint is prepared, backed to depth and sealed in the product the specification names.
  6. We close out snagging and hand over with a 12-month guarantee.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Sites and facades in and around Morton

With the shore within about 1 mile, Morton counts as a coastal location. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. There are a good number of hotels within about 2 miles of Morton. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

Units on estates such as Spithead Business Centre (2.5 miles south-west of Morton) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Projects at schools like Brading Church of England Controlled Primary School work to term dates, so mastic is programmed tightly.
