Mastic sealing across Horseman Side

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

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • The site’s rules and procedures
  • Quantities, in metres or numbers
  • Phasing around occupants
  • Specialist products, such as fire-rated or hygienic sealants

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

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

  • Any dates the work must fit around
  • Whether an asbestos survey exists
  • Clear photographs of the problem areas
  • The postcode of the building

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or send details through our quote form with what you know.

How we handle mastic sealing in Horseman Side

Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. If you’re dealing with estate-wide sealant that is simply worn out and leaks at window and door perimeters, we can put it right. A specialist sealant contractor works differently from a general builder: on jobs in Horseman Side, preparation and product choice get the time they need.

Around smaller places like Horseman Side, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

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.

Questions about Horseman Side

Is Horseman Side off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Do you take on block-wide or estate-wide mastic work in Horseman Side?

Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.

What paperwork can you provide?

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

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can you seal joints high up on a block?

Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.

What guarantee do you give on resealing?

There is a 12-month guarantee on our workmanship, backed by public liability insurance.

For owners and agents in Horseman Side

Horseman Side is about 17 miles from central London. Within reach of London, blocks run by agents and associations are common around stations. Horseman Side is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

Churches, halls and community buildings such as Church of St Paul are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. With historic buildings such as Hill Hall (4.2 miles north-west of Horseman Side) in the wider area, owners of older properties around Horseman Side should expect mastic to need a product that suits old masonry. For a school such as Drapers' Academy, perimeter mastic on windows and doors is a holiday job.

Site staff or a sealant specialist?

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

After the work

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

  • Make it easy for occupiers to report draughts
  • Check sealant joints during planned building inspections
  • Check the asbestos register before any old mastic is disturbed
  • Reduce knocks to communal area joints

Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.

Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.

Surface by surface

Communal areas

Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Tidy, sound joints keep them looking cared for.

Window and door perimeters on blocks

On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.

What sealant work can’t fix

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

  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Failed window or door frames, which need a window contractor

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

What we seal

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