Planned mastic for Havering-atte-Bower portfolios
Blocks in London are usually run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We work to your notice and access plan.
For a school such as Dame Tipping Church of England Primary School, perimeter mastic on windows and doors is a holiday job. Older buildings near Havering-atte-Bower, from historic houses such as Hare Hall (2.6 miles south of Havering-atte-Bower) to more modest stock, need compatible products when frames are resealed.

Mastic sealing in Havering-atte-Bower, done properly
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. If you are dealing with open joints in brickwork or panels and communal area joints that look neglected, we can help, on shopfronts below residential blocks, communal kitchens and washrooms and window and door perimeters on blocks alike. Most enquiries from Havering-atte-Bower start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Questions about Havering-atte-Bower
Will you price a mastic programme across our Havering-atte-Bower portfolio?
Yes. Planned programmes across a building, block or estate are a core part of this service. Send the addresses and photos and we’ll give a fixed quote.
Will you take on a block within reach of Harold Wood station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Do you work with property factors and landlords?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.

What else we do in Havering-atte-Bower
What happens if it’s left?
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Why us?
- Public liability insurance in place
- One contact handling all your sites
- Matching to RAL references, product permitting
- A fixed quote before work starts
Take a look at what affects the cost and our accreditations and insurance.
Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Share your contractor requirements early
- Track which buildings were done and when
- Protect low-level joints in entrances
- Include mastic in your cyclical inspections
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.
From enquiry to sign-off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. In Havering-atte-Bower, 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.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Point out any areas we must not close
- Tell us your opening times and when work is allowed
- Clear stock, furniture or equipment away from the joints

Advice
Do you need mastic sealing in Havering-atte-Bower?
Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Regular cleaning wears them further.
What tends to prompt an enquiry:
- Patchy repairs in mismatched sealant
- Communal area joints that look neglected
- Mastic failing across several blocks on an estate
- Open joints in brickwork or panels
If you look after a block within reach of Harold Wood station (2.7 miles south-east of Havering-atte-Bower), frame and balcony mastic can be renewed on one programme.

Quoting for work in Havering-atte-Bower
Each job is priced on its own details. The main factors are:
- Removal of failed or old sealant
- The total length or number of joints
- Phasing around occupants
- Access and working height
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Before you send an enquiry
A good diagnosis starts with the right details. Tell us:
- A wide shot and a close-up of the area
- Asbestos survey details if the building is older
- Approximate linear metres or a joint schedule
- The site address and postcode
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to speak to us on 01277 525 020 or use the quote form.
For managing agents and facilities managers
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.
Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
