Mastic sealing in Rowhook

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

Mastic sealing in Rowhook

We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. We work on shopfronts below residential blocks, balcony and threshold joints and communal kitchens and washrooms, and what we are called in for most is repeated reactive repairs to the same buildings and open joints in brickwork or panels. Looking for mastic applicators who cover Rowhook? We have been sealing commercial buildings since 2005.

Owners and agents with buildings around smaller places such as Rowhook tend to manage small terraces of association properties, converted barns and commercial units. 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: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

On site: what to expect

The first thing on site is a walk round with your contact, 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. For work around Rowhook, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

What we need from you

  • Let building users know which areas are affected
  • Tell us which areas need to stay in use
  • Flag any permit to work we’ll need

What affects the price in Rowhook

What shapes the price:

  • The size and state of each joint
  • Phasing around occupants
  • How much existing material needs removing
  • The product specified

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Sending details for a quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Photos of the joints, close up and from further back
  • Approximate linear metres or a joint schedule
  • Specification clauses that apply
  • When you need the work done

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or send photos by email.

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Glazing that needs replacing
  • Leaks from above rather than through a joint
  • Failed window or door frames, which need a window contractor

If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think before you book.

Surfaces we seal

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

Rowhook: questions and answers

Will you take on work at estates like Nowhurst Business Park, close to Rowhook?

Yes. Estates, retail parks and business parks around Rowhook, Nowhurst Business Park among them, are all within reach. A few photos and the unit address let us price the work.

Do you work in occupied care homes around Rowhook?

Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.

What about access for upper-floor joints?

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 tell you how we’d approach it.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Is Rowhook in your area?

Yes. Sites across Rowhook are covered.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

What the job involves on each surface

Tenement and older buildings

Traditional buildings have joints that need a careful approach. We look at the substrate before choosing a sealant.

Estate-wide resealing programmes

Consistent products and colours across an estate make future maintenance simpler.

Building owners, agents and FMs in Rowhook

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Rowhook can form part of a wider programme across West Sussex.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Maintenance after handover

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Protect low-level joints in entrances
  • Share the asbestos register when you send details
  • Avoid piecemeal callouts where you can
  • Share your contractor requirements early

Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.

One failed perimeter normally means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.

For owners and agents in Rowhook

Rowhook is about 31 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Three care or nursing homes sit less than 2 miles from Rowhook. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents.

If you look after a block within reach of Warnham station (3 miles east of Rowhook), frame and balcony mastic can be renewed on one programme. Site managers at schools like Farlington School can fit frame mastic into the summer works.
