How we handle mastic sealing in Detling

Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. If you have water getting in round frames after rain and open joints in brickwork or panels, we can help, whatever the surface. Searching for sealant specialists in Detling? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

For buildings around smaller places like Detling, we group work so one trip covers it. Photos of each elevation help us quote accurately.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Diagnose, treat, sign off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. For a building around Detling, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

Advice

Planned mastic for Detling portfolios

Detling is about 32 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Rainfall across the South East, Detling included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.

Owners of student blocks near University for the Creative Arts, 3.5 miles to the south-west of Detling, can schedule frame and external mastic for the summer vacation. For a school such as Valley Park School, perimeter mastic on windows and doors is a holiday job.

Detling is about 3 miles north-east of Maidstone, in Kent. We send applicators to Detling for mastic joints, handled exactly as we handle every other area. 931 places across Kent fall within our area, Detling among them. We also cover London, around 32 miles from Detling.

Anyone looking for mastic sealing in ME14 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. We cover commercial and managed buildings on The Street, Princes Way and Queens Way and the roads nearby. Sites close to Detling are covered too, including Thurnham (1 mile south-east), Grove Green (1 mile south-west), Harbourland (1 mile west), Weavering (2 miles south) and Bearsted (2 miles south). Bigger towns within reach include Maidstone (3 miles south-west), Sittingbourne (8 miles north-east), Gravesend (12 miles north-west), Tonbridge (14 miles south-west), Faversham (14 miles east) and Northfleet (14 miles north-west).

What’s near Detling

Locally, jobs take us to sites close to The Larches and The Cock Horse pub and the streets around them. The nearest railway station is Bearsted station, about 1.4 miles south of the centre. A little further out are KIMS hospital (0.8 miles south-west) and The Mall Maidstone (2.4 miles south-west). The countryside around Detling includes Burham Down and Detling Hill.

Cost factors for mastic joints

We price every job individually. The main factors are:

  • Any access equipment needed
  • Joint width, depth and condition
  • Travel to remote or island sites
  • Whether the work must be split into stages

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.

Before you send an enquiry

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

  • Whether an asbestos survey exists
  • How the joints are reached, and at what height
  • The site address and postcode
  • Rough lengths or quantities, or drawings if you have them

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Why deal with it now?

Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. One visit to deal with every failing joint makes more sense than several trips to a place like Detling, rather than one at a time. Send photos of each area and we will quote for the lot.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why us?

  • One number for every site we cover
  • RAL and finish matching where the product range allows
  • Constructionline member
  • Sealing commercial buildings since 2005

When to call us in Detling

We often find joints filled solid with no backing rod so the mastic is bonded on three sides. It can’t stretch properly and it tears.

Site and facilities staff are often the first to spot these:

  • The same joint failures repeated across a portfolio
  • Complaints coming in block by block
  • Movement joints with sealant missing
  • Occupiers reporting cold air round windows

For owners of several units at places like Viewpoint Industrial Estate, 1.4 miles west of Detling, one programme can deal with frame and external mastic across the lot.

What your quote should include

  • Proof of insurance
  • The terms of the workmanship guarantee
  • Their approach to joint depth and backing
  • Is the sealant right for the movement and the substrate?

Our contractor checklist

Should maintenance staff do it?

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Masonry that has broken away beside the joint
  • Water coming in from the roof or rainwater goods
  • Asbestos-containing sealant, which we don’t remove

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

Joints and surfaces we work on

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

Your questions answered

Will you take on a block within reach of Bearsted station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.

Is Viewpoint Industrial Estate, near Detling, within your area?

Yes. Our area takes in Detling and its surroundings, with estates and business parks such as Viewpoint Industrial Estate included. Photos and a short description are enough for a first look.

Do you work to architects’ specifications?

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

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What about access for upper-floor joints?

We talk through access for each building when we quote. Tell us the building height and any access already in place and we will confirm the approach in the quote.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Do you cover Detling?

Yes. We take on work across Detling.
