Looking after buildings in and around North Street

North Street lies roughly 45 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations. North Street is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.

For agents with blocks near Faversham station, which lies north of North Street, a block-wide mastic programme deals with frames, balconies and entrances in one go. Older buildings near North Street, from historic houses such as Belmont House and Gardens (2 miles south-west of North Street) to more modest stock, need compatible products when frames are resealed. If you’re responsible for a building such as Church of St James, frame and door mastic needs the same attention as any other property.

North Street is about 2 miles south of Faversham, in Kent. Our applicators travel to North Street for work on mastic joints. We work across 931 places in Kent. We also cover London, around 45 miles from North Street.

Mastic sealing in North Street, done properly

On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. We work on external wall and movement joints, shopfronts below residential blocks and communal kitchens and washrooms, and the failures we’re asked to look at most are old repairs sealed over failed mastic and damaged joints in communal entrances and corridors. One point of contact handles commercial sealant work in North Street from the first photos to the final walk-round, for single jobs and planned programmes alike.

In and around smaller places like North Street, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Why act early in North Street

Failed perimeter mastic lets cold air in around frames and the windows normally get the blame. In many cases, new perimeter sealant deals with it when the frames themselves are sound. One visit to deal with every failing joint makes more sense than several trips to a place like North Street. Send photos of each area and we’ll quote for the lot.

Quantities, awkward access and phased working 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 us?

  • Workmanship guaranteed for 12 months
  • CHAS accredited contractor
  • Constructionline member for supplier checks
  • Public liability insurance in place

For managing agents and facilities managers

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, plus a 12-month guarantee.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

North Street: questions and answers

Can you quote for mastic across several buildings in and around North Street?

Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we’ll give a fixed quote.

Is North Street off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, 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.

Can people stay in the building while you reseal?

Residents and tenants carry on as normal. If any flats or units need access, we will tell you in advance so it can be arranged.

What guarantee do you give on resealing?

Our workmanship carries a 12-month guarantee and we hold public liability insurance.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

What the job involves on each surface

External movement joints

The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.

Window and door perimeters on blocks

We typically work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.

Cost factors for mastic joints

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Removal of failed or old sealant
  • Distance, for remote addresses
  • Induction, permit and paperwork requirements
  • Joint width, depth and condition

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Any dates the work must fit around
  • Where the site is, with the postcode
  • Asbestos survey details if the building is older
  • Clear photographs of the problem areas

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. If you have questions first, call the office on 01277 525 020 or send details through our quote form.

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 normally takes a few days for most blocks, with larger programmes scheduled building by building, and we clear our waste as we work. For work around North Street, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First we look at the mastic on each building and note what needs replacing.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  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. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Before we start on site

  • Have the specification and drawings to hand
  • Flag any permit to work we’ll need
  • Tell us which areas need to stay in use

Request a quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
