Mastic sealing in Brunswick Park, done properly

In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. The enquiries we see most involve a mix of products and colours from past repairs and window mastic that has split and shrunk, on shopfronts below residential blocks, communal entrances and stairwells and communal kitchens and washrooms. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Brunswick Park is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

London’s ULEZ covers every borough, and parking and loading rules vary street by street. For block-wide work, a place to park and store materials saves time on every visit.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Building owners, agents and FMs in Brunswick Park

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Common questions from Brunswick Park clients

Can you cope with the access rules in a London building?

Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them.

Do you cover business parks and estates near Brunswick Park, such as North London Business Park?

Yes. We cover Brunswick Park and the area around it, including industrial estates, business parks and retail parks such as North London Business Park. Send details of the unit and the work through our quote form for a quick quote.

Is Brunswick Park in your area?

Yes. We cover Brunswick Park and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. For a quote, give us a call on 01277 525 020 or email us.

What paperwork can you provide?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.

How do we ask for a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or email the details over. Include photos or drawings if you have them.

Can you seal joints high up on a block?

It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.

Can you reseal a whole block or estate?

Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.

General trades versus a specialist

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Planned mastic for Brunswick Park portfolios

There are nine care or nursing homes within about 2 miles of Brunswick Park. Care home owners need frame and external mastic kept sound without unsettling residents. London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We fit the programme to your notice periods.

If you manage student housing near a university such as Middlesex University, 4.5 miles south-west of Brunswick Park, the summer turnaround is the time for mastic. For a school such as St Andrew the Apostle Greek Orthodox School, perimeter mastic on windows and doors is a holiday job. Buildings close to stations like New Southgate station, 0.9 miles south of Brunswick Park, are often flats over shops, with frame mastic to keep sound.

Keeping the joints sound

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Group repairs into a planned programme
  • List the paperwork your organisation requires when you send details
  • Reduce knocks to communal area joints
  • Make it easy for occupiers to report draughts

Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.

One failed perimeter typically means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.

Different surfaces, different methods

Estate-wide resealing programmes

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

External movement joints

The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Whether old sealant has to be cut out first
  • How accessible the joints are
  • Quantities, in metres or numbers
  • The site’s rules and procedures

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Details that help us quote

A few photographs plus some basic facts will normally do. It helps to include:

  • Photos of the joints, close up and from further back
  • Drawings or a marked-up plan, if available
  • Asbestos survey details if the building is older
  • Your programme or deadline

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or use the quote form.

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. In Brunswick Park, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  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.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Point out parking and an unloading spot
  • Tell us which areas need to stay in use
