Your questions answered

Is Headley off your patch?

Not at all. Headley is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you work at a site such as New Greenham Business Park, by Headley?

Yes. We cover Headley and the area around it, including industrial estates, business parks and retail parks such as New Greenham Business Park. Send details of the unit and the work through our quote form for a quick quote.

Do you seal facades in winter?

Rain and frost can pause external sealing. We plan for weather and keep you updated as the work goes on.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Is colour matching possible?

It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

About our facade sealing in Headley

Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces. If you have leaks at window and door perimeters and patch repairs that keep failing, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Headley is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Conversions of older rural buildings near smaller places such as Headley bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near Headley need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Preparing the site

  • Move anything stored against the joints
  • Explain the parking and delivery arrangements
  • Have the specification and drawings to hand

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Signs you need facade sealing in Headley

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.

It’s worth sending us details if you spot any of the following:

  • Facade joints cracked through the middle
  • Previous reseals run over old sealant
  • Hard, chalky sealant that no longer flexes
  • Discoloured or dirty facade joints

Units on estates such as New Greenham Business Park (1.5 miles north-west of Headley) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Comparing quotes

  • Their pre-qualification and accreditations
  • Is the sealant right for the movement and the substrate?
  • Whether old or failed sealant will be cut out, not overlaid
  • What level of public liability insurance do they hold?

Choosing a commercial sealant contractor

What the job involves on each surface

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification with a product suited to glazing perimeters.

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported first.

Facade sealing around Headley: how the place shapes the job

The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. At about 51 miles from central London, Headley is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

Projects at schools like Cheam School work to term dates, so mastic is programmed tightly. Older buildings in the area around Headley, such as Shaw House (4.4 miles north-west of Headley), need care when sealed: the product has to suit soft or historic materials.

Headley is about 3 miles south of Thatcham, in Hampshire. Anywhere in RG19, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 723 places in Hampshire. Our Reading page has more on work in that area.

Why deal with it now?

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Halls, stores and units around places like Headley may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Honest limits

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Damaged frames that need replacing
  • Damp caused by condensation inside the building
  • Specialist high-level access methods

Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly.

Joints and surfaces we work on

  • Coping and flashing joints
  • Perimeter joints where frames meet the structure
  • Window and door perimeters
  • Cladding panel joints
  • Stone and brick facade joints
  • Shopfront frames

What affects the price in Headley

These are the things that shape the price:

  • Whether old sealant has to be cut out first
  • Site requirements such as inductions and permits
  • The size and state of each joint
  • The total length or number of joints

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Before you send an enquiry

A few photos plus some basic facts will normally do. Please tell us:

  • What the building is and how it’s used
  • When you need the work done
  • How the joints are reached, and at what height
  • The asbestos register, for older buildings

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
