Your questions answered

Will you take on work at estates like Lordswood Industrial Estate, close to Lordswood?

Yes. Estates, retail parks and business parks around Lordswood, Lordswood Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.

Is a smaller place like Lordswood outside your area?

No. Places such as Lordswood are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can people stay in the building while you reseal?

The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.

Do you supply RAMS and insurance details?

We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

What will the job cost?

Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or send details through our quote form with a description of the work.

What guarantee do you give on resealing?

A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.

Do you do block-wide mastic programmes?

We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

Mastic sealing for commercial buildings in Lordswood

Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. We work on window and door perimeters on blocks, external wall and movement joints and communal entrances and stairwells, and the failures we’re asked to look at most are occupiers reporting cold air round windows and communal area joints that look neglected. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Lordswood it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Places the size of Lordswood usually have some housing association stock, small blocks and mixed-use buildings. Their window perimeters and external joints need renewing as the mastic ages.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Commercial clients in Lordswood

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.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Different surfaces, different methods

Tenement and older buildings

Older mastic can contain asbestos, so we check the asbestos register or survey first. Suspect material is tested before work continues.

Estate-wide resealing programmes

Housing associations and agents often manage many similar blocks. Each block is priced and scheduled in order.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Leaks from above rather than through a joint
  • Glazing that needs replacing
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

What we seal

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

Blocks and managed buildings in Lordswood

Lordswood is about 30 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.

Landlords with units on estates such as Lordswood Industrial Estate, 0.5 miles south of Lordswood, can bring frame, door and external mastic across several units into one programme. If you look after a block within reach of Chatham station (3.2 miles north of Lordswood), frame and balcony mastic can be renewed on one programme. Owners of student blocks near University for the Creative Arts - Rochester (to the north-west of Lordswood) can schedule frame and external mastic for the summer vacation.

What happens if it’s left?

Failed perimeter mastic lets cold air in around frames and the windows usually get the blame. In many cases, new perimeter sealant deals with it when the frames themselves are sound. Small buildings around Lordswood suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

Pricing mastic joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Why appoint us

  • Failed material removed, not covered up
  • Our applicators hold CSCS cards
  • Over 20 years of commercial sealing
  • Workmanship guaranteed for 12 months

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

From enquiry to sign-off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a day or two for a single block, longer for an estate programme, and our waste is bagged and taken away as we go. What matters most for a job in Lordswood is a clear list of what needs doing, so send photographs of each area. You will then get a fixed price for the work.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Before we start on site

  • Point out parking and an unloading spot
  • Let building users know which areas are affected
  • Point out any areas we must not close
