Mastic sealing for commercial buildings in The Hangers

On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Entrances and stairwells are kept in use throughout. We work on window and door perimeters on blocks, communal entrances and stairwells and shopfronts below residential blocks, and the failures we are asked to look at most are worn sealant at communal door frames and leaks at window and door perimeters. Looking for mastic applicators who cover The Hangers? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

For buildings around smaller places like The Hangers, we group work so one trip covers it. Send photos of the frames and joints and we will give a fixed quote.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Diagnose, treat, sign off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re 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 The Hangers, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. A fixed quote follows, split by block or building if that suits you.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Before we start on site

  • Agree which areas must stay open
  • Point out parking and an unloading spot
  • Send your site hours and access windows

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

For owners and agents in The Hangers

The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building normally need attention first. The Hangers lies roughly 60 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.

If you own or manage units on a site such as Swanmore Business Park, which lies south of The Hangers, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. For agents with blocks near Botley station (4.7 miles south-west of The Hangers), a block-wide mastic programme deals with frames, balconies and entrances in one go. Schools and community buildings such as Bishops Waltham Infant School need frame and external mastic kept sound like any building.

The Hangers is about 6 miles north-east of Hedge End, in Hampshire. Looking for mastic sealing in The Hangers? We can help. We work across 723 places in Hampshire, large and small. For work in that direction, see our Southampton page, about 10 miles away.

The Hangers: questions and answers

Will you take on work at estates like Swanmore Business Park, close to The Hangers?

Yes. Estates, retail parks and business parks around The Hangers, Swanmore Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Can you quote for a block close to Botley station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.

How soon can the area be used again?

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

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

What paperwork can you provide?

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?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Quoting for work in The Hangers

Each job is priced on its own details. The main factors are:

  • Removal of failed or old sealant
  • Induction, permit and paperwork requirements
  • Any access equipment needed
  • Working within restricted access windows

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What we need to price the job

We can often quote from photos and a few details. Please tell us:

  • Any specification or named product
  • Your programme or deadline
  • Clear photographs of the problem areas
  • How the joints are reached, and at what height

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or email a schedule or drawings with what you know.

Surface by surface

Planned maintenance

Resealing can be scheduled alongside other planned works on a timetable you set.

External movement joints

Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.

When something else is needed

We check first that sealant really is the fix. It isn’t the answer for:

  • Substrate edges that need repairing first
  • Glazing that needs replacing
  • Frames that are rotten, warped or broken

If in doubt, speak to us on 01277 525 020 or email us and we will say what we think.

Where we work in The Hangers

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

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Start inspections with the most exposed faces
  • Check the asbestos register before any old mastic is disturbed
  • Log resealing dates block by block
  • Encourage occupiers to report problems at frames

Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.

Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
