About our mastic sealing in Gaskins

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. If you have brittle perimeter mastic across a building and old repairs sealed over failed mastic, we can put it right. Looking for mastic applicators who cover Gaskins? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Owners and agents with buildings around smaller places such as Gaskins tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Signs you need mastic sealing in Gaskins

Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Regular cleaning wears them further.

Any of the following is a good reason to get the joints checked over:

  • Damaged joints in communal entrances and corridors
  • Draughts at frames across a block
  • Damp patches beside frames
  • No planned programme for sealant

Churches, halls and community buildings such as St Catherine-by-the-Green are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Comparing quotes

  • What level of public liability insurance do they hold?
  • Whether their applicators hold CSCS cards
  • Their approach to joint depth and backing
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

On site: what to expect

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Gaskins are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

Before we start on site

  • Share the asbestos register for older buildings
  • Have the specification and drawings to hand
  • Let us know about inductions and permits

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Questions about Gaskins

Will you take on work at estates like Ryde Business Park, close to Gaskins?

Yes. We cover Gaskins and the area around it, including industrial estates, business parks and retail parks such as Ryde Business Park. To start, just speak to us on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Do you work for managing agents with blocks near Brading station?

Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.

How do you reach windows on upper floors?

It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.

Do you work in Gaskins?

Yes. Gaskins falls within our area, and you can ring 01277 525 020 or use the quote form to get started.

Can you reseal a whole block or estate?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.

Can you send RAMS and CSCS details before starting?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Frames, entrances and external joints in Gaskins

With the shore within about 2 miles, Gaskins counts as a coastal location. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Gaskins sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.

Landlords with units on estates such as Ryde Business Park, 2.2 miles north-west of Gaskins, can bring frame, door and external mastic across several units into one programme. With historic buildings such as Nunwell House (1.7 miles south-west of Gaskins) in the wider area, owners of older properties around Gaskins should expect mastic to need a product that suits old masonry.

Gaskins is about 3 miles south-east of Ryde, in the Isle of Wight.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Asbestos-containing sealant, which we don’t remove
  • Water coming in from the roof or rainwater goods
  • Substrate edges that need repairing first

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.

Surfaces we seal

  • Communal entrances and stairwells
  • Balcony and threshold joints
  • External wall and movement joints
  • Shopfronts below residential blocks
  • Window and door perimeters on blocks
  • Communal kitchens and washrooms

Why act early in Gaskins

Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it when the frames themselves are sound. Halls, stores and units around places like Gaskins may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Why clients in Gaskins choose us

  • Our applicators hold CSCS cards
  • Clear, fixed quotes
  • Colours confirmed for the specified product
  • Products installed to the manufacturer’s instructions

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Ask residents or tenants to report leaks and draughts early
  • Make mastic part of routine maintenance checks
  • List the paperwork your organisation requires when you send details
  • Look at the sunniest and most exposed elevations first

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.
