Mastic sealing for Horton Heath sites

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

From enquiry to sign-off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. Several jobs near Horton Heath can be grouped on one trip. Tell us your site hours and we’ll plan around them.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Getting the site ready

  • Point out parking and an unloading spot
  • Make sure the joints can be reached
  • Let us know about inductions and permits

Getting a fixed quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Advice

Mastic sealing in Horton Heath, done properly

For blocks and buildings in Horton Heath and across Hampshire, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote, and site visits can be arranged. We work on external wall and movement joints, shopfronts below residential blocks and communal kitchens and washrooms, and the failures we are asked to look at most are open joints in brickwork or panels and old repairs sealed over failed mastic. One point of contact handles commercial sealant work in Horton Heath from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Converted and older buildings in and around Horton Heath often put modern windows into old walls. The mastic there needs to suit both surfaces.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How the quote is worked out

What shapes the price:

  • How much there is to seal
  • Location, for remote and island sites
  • Working within restricted access windows
  • The site’s rules and procedures

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode
  • The asbestos register, for older buildings
  • Any specification or named product

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.

Building owners, agents and FMs in Horton Heath

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

What the job involves on each surface

Planned maintenance

Planned resealing replaces emergency callouts and spreads the work.

External movement joints

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

Looking after buildings in and around Horton Heath

The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Central London is about 64 miles from Horton Heath. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate.

Trustees of buildings like Church of the Holy Cross can bring frame and external mastic into a planned maintenance list. Landlords with units on estates such as Deer Park Farm Industrial Estate, 0.9 miles north-east of Horton Heath, can bring frame, door and external mastic across several units into one programme. Student accommodation around universities such as University of Southampton (to the west of Horton Heath) is usually managed block by block, which suits a planned mastic programme.

FAQs: Horton Heath

Will you take on work at estates like Deer Park Farm Industrial Estate, close to Horton Heath?

Yes. Our area takes in Horton Heath and its surroundings, with estates and business parks such as Deer Park Farm Industrial Estate included. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Will you take on a block within reach of Hedge End station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Do you work with property factors and landlords?

Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn with dates agreed in advance.

Do you do block-wide mastic programmes?

We can. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Do you check for asbestos in old sealant?

In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

What we can’t put right

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Leaks from above rather than through a joint
  • Broken glass or failed sealed units
  • Substrate edges that need repairing first

If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
