Mastic sealing in Upper Halling, done properly

On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Entrances and stairwells are kept in use while we work. We work on window and door perimeters on blocks, shopfronts below residential blocks and communal entrances and stairwells, and what we’re called in for most is repeated reactive repairs to the same buildings and communal area joints that look neglected. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Upper Halling is the same: the right product in a properly prepared joint.

Rural conversions near places like Upper Halling often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Removal of failed or old sealant
  • Backing rod, priming and other preparation
  • Access and working height
  • Whether the work must be split into stages

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Before you send an enquiry

We can often quote from photos and a few details. Please tell us:

  • Your programme or deadline
  • Asbestos survey details if the building is older
  • The product your specification calls for
  • Access details, including height

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or use the quote form.

Looking after the joints

A few simple habits keep the new joints working:

  • Make mastic part of routine maintenance checks
  • Track which buildings were done and when
  • Plan resealing building by building rather than complaint by complaint
  • Share your contractor requirements early

Keep records of when each building was resealed. It helps plan the next round and gives you a history.

One failed perimeter typically means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.

Signs you need mastic sealing in Upper Halling

Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone and the repair soon fails.

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

  • Draught complaints from residents or tenants
  • Communal area joints that look neglected
  • Damp patches beside frames
  • The same joint failures repeated across a portfolio

Owners of student blocks near University for the Creative Arts - Rochester (to the north-east of Upper Halling) can schedule frame and external mastic for the summer vacation.

What your quote should include

  • What level of public liability insurance do they hold?
  • How the existing material will be dealt with
  • What site paperwork they can supply
  • How joint depth will be controlled

How to choose a sealant contractor

How a job runs

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Upper Halling, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

Before we start on site

  • Send your site hours and access windows
  • Send asbestos survey details if the building is pre-2000
  • Tell us which areas need to stay in use

Ask for a quote

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.

Advice

Block-wide mastic in Upper Halling

The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Upper Halling lies roughly 25 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.

For owners of several units at places like New Hythe Business Park, which lies south-east of Upper Halling, one programme can deal with frame and external mastic across the lot. For a school such as Halling Primary School, perimeter mastic on windows and doors is a holiday job.

Upper Halling is about 4 miles south-west of Rochester, in Medway. Businesses, contractors and managing agents in Upper Halling can call on us for mastic joints. Upper Halling is one of 54 places in Medway on our list. We also cover London, around 25 miles from Upper Halling.

Questions we’re asked in Upper Halling

Is New Hythe Business Park, near Upper Halling, within your area?

Yes. Our area takes in Upper Halling and its surroundings, with estates and business parks such as New Hythe Business Park included. To start, just call 01277 525 020 or email the details over with the unit, the joints involved and your access times.

We manage a building near Halling station. Can you help?

Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.

How many days will you need on site?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What if the old mastic contains asbestos?

Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.

Will residents or tenants be disturbed?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.

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.
