Mastic sealing around Hammer: how the place shapes the job

Hammer lies roughly 40 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations. The 2 miles around Hammer include three care or nursing homes. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.

If you look after a block within reach of Haslemere station, 1.5 miles to the east of Hammer, frame and balcony mastic can be renewed on one programme. Schools and community buildings such as Woolmer Hill School need frame and external mastic kept sound like any building. Trustees of buildings like St. Stephen's Church can bring frame and external mastic into a planned maintenance list.

About our mastic sealing in Hammer

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. The enquiries we see most involve failed external movement joints and old repairs sealed over failed mastic, across external wall and movement joints, balcony and threshold joints and communal kitchens and washrooms. For commercial sealant work in Hammer, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In and around smaller places like Hammer, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

What our 12-month guarantee covers is the way we did the job: 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 Hammer

Do you cover business parks and estates near Hammer, such as Kings Road Industrial Estate?

Yes. Our area takes in Hammer and its surroundings, with estates and business parks such as Kings Road Industrial Estate included. A few photographs and the unit address let us price the work.

Is Hammer off your patch?

Not at all. Hammer is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

Will you quote for a small job?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

What do you charge?

There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.

What happens if it’s left?

A bead run over old mastic can look like a repair. It doesn’t bond and typically fails within a short time. Cutting out and resealing properly does it once. Older rural buildings around Hammer move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why clients in Hammer choose us

  • Colours confirmed for the specified product
  • Products installed to the manufacturer’s instructions
  • Commercial sealant work since 2005
  • A fixed quote before work starts

Take a look at what affects the cost or how we’re accredited.

What the job involves on each surface

Window and door perimeters on blocks

Blocks have a mix of frame materials, so the grade we pick has to bond to frame and wall alike. We will confirm the colours available for the specified product.

Estate-wide resealing programmes

An estate of similar buildings suits a rolling programme. We quote building by building and work through them in turn.

When it isn’t the sealant

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

  • Frames that are rotten, warped or broken
  • Glazing that needs replacing
  • Asbestos-containing sealant, which we don’t remove

Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly before you book.

Surfaces we seal

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

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Protect low-level joints in entrances
  • Look at the sunniest and most exposed elevations first
  • Make it easy for occupiers to report draughts
  • Track which buildings were done and when

Keep records of when each building was resealed. That makes future programmes easier to plan and shows what was done.

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

What affects the price in Hammer

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

  • Whether old sealant has to be cut out first
  • The total length or number of joints
  • The site’s rules and procedures
  • The size and state of each joint

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • Rough lengths or quantities, or drawings if you have them
  • How the joints are reached, and at what height

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or use the quote form to discuss it first.

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking one or more days per building, depending on the joint lengths and the access. Smaller jobs around Hammer can be grouped with others nearby. You will have a fixed quote before work starts.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.
