Mastic sealing for commercial buildings in Biggin Hill
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. If you have estate-wide sealant that is simply worn out and communal area joints that look neglected, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Biggin Hill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
For managing agents in Biggin Hill, resident access, notice periods and the building’s rules shape the job. Work is planned with the agent so residents get notice and access is arranged in advance.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sets the cost
The price varies from site to site. Expect it to depend on:
- Specialist products, such as fire-rated or hygienic sealants
- Removal of failed or old sealant
- Site requirements such as inductions and permits
- The total length or number of joints
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
Sending details for a quote
Whether it’s one area or a whole building, these details speed things up:
- How the joints are reached, and at what height
- Clear photos of the problem areas
- The product your specification calls for
- What the building is and how it’s used
For a fixed quote, phone 01277 525 020 or email a schedule or drawings. Our quote form is another easy route.

Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Make it easy for occupiers to report draughts
- Group repairs into a planned programme
- Start inspections with the most exposed faces
- Track which buildings were done and when
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.
Planned mastic for Biggin Hill portfolios
London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. Our programme follows the access you agree with residents.
Property owners at sites such as Biggin Hill Airport Trading Estate (0.6 miles north of Biggin Hill) can have mastic renewed between lettings. Historic properties like Down House, 1.7 miles to the north-east of Biggin Hill, show the age of some local stock, where frame mastic must suit soft brick or stone.
Biggin Hill is about 6 miles east of Caterham, in Greater London. We cover commercial sites throughout Biggin Hill, whether it’s a single job or part of a planned programme.

Commercial sites across TN16 and BR6 are covered. For a building on Rushdene Walk, Mount Pleasant and Stock Hill or nearby, send details and we will quote for mastic joints.

Commercial clients in Biggin Hill
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
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.
Questions about Biggin Hill
Do you work for managing agents with blocks near Woldingham station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Will you take on work at estates like Biggin Hill Airport Trading Estate, close to Biggin Hill?
Yes. Our area takes in Biggin Hill and its surroundings, with estates and business parks such as Biggin Hill Airport Trading Estate included. A few photos and the unit address let us price the work.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
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 there are no surprises.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
Signs you need mastic sealing in Biggin Hill
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone and the repair soon fails.
Common reasons buildings call us in:
- Repeated reactive repairs to the same buildings
- Movement joints with sealant missing
- Mastic failing across several blocks on an estate
- A mix of products and colours from past repairs
Buildings close to stations like Woldingham station (3.8 miles south-west of Biggin Hill) are often flats over shops, with frame mastic to keep sound.
Before you book anyone
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Their pre-qualification and accreditations
- How they’ll work around occupants
- Which product they’ll use, and why it suits the joint
How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. All of Greater London is in the ULEZ, and kerbside space in Biggin Hill can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Point out parking and an unloading spot
- Send your site hours and access windows
- Have the specification and drawings to hand

Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
