Blocks and managed buildings in Debden

At about 13 miles from central London, Debden is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.

Schools and community buildings such as Thomas Willingale Primary School and Nursery need frame and external mastic kept sound like any building. If you look after a block within reach of Chingford station, 3.3 miles to the west of Debden, frame and balcony mastic can be renewed on one programme. Trustees of buildings like Church of St Nicholas can bring frame and external mastic into a planned maintenance list.

Mastic sealing in Debden, done properly

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. We work on balcony and threshold joints, window and door perimeters on blocks and external wall and movement joints, and the failures we’re asked to look at most are damaged joints in communal entrances and corridors and water getting in round frames after rain. Whoever orders the work in Debden, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Owners with buildings around smaller places like Debden often group mastic work so one visit covers several properties. Send the addresses and photographs and we’ll quote for all of them together.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

From enquiry to sign-off

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a site in Debden, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

Getting the site ready

  • Point out parking and an unloading spot
  • Confirm the product named in the specification
  • Let building users know which areas are affected

Quotes

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.

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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.

For managing agents and facilities managers

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

Common questions from Debden clients

Do you work for managing agents with blocks near Chingford station?

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

Do you cover business parks and estates near Debden, such as Epping Forest Shopping Park?

Yes. Our area takes in Debden and its surroundings, with estates and business parks such as Epping Forest Shopping Park included. Send details of the unit and the work through our quote form for a quick quote.

How do you reach windows on upper floors?

It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.

Do you work for managing agents and housing associations?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.

How do you handle work on occupied blocks?

We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Water coming in from the roof or rainwater goods
  • Broken glass or failed sealed units
  • Failed window or door frames, which need a window contractor

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

What we seal

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

Aftercare for building managers

For the best life from the joints:

  • Keep bins and bikes away from communal door frames
  • Plan resealing building by building rather than complaint by complaint
  • Log resealing dates block by block
  • Start inspections with the most exposed faces

If paintable sealant was used, decoration can follow once it has cured. Silicone normally can’t be painted, so keep decorators off it.

Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing and the job grows.

What the job involves on each surface

External movement joints

Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.

Tenement and older buildings

Older mastic can contain asbestos and the register is checked before anything is disturbed. If it’s suspected, work stops until it’s tested.
