How we handle mastic sealing in Horley
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. Communal entrances and stairs stay usable while we work. If you have draughts at frames across a block and movement joints with sealant missing, we can put it right, on external wall and movement joints, balcony and threshold joints and communal kitchens and washrooms alike. A specialist sealant contractor works differently from a general builder: in Horley, that means joint design, primers and backing rod as standard.
In and around smaller places like Horley, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Work for main contractors and building owners
Building owners and managing agents use us on everything from one building to a spread of sites around Horley. Several sites can go on one quote, so there’s one set of paperwork to deal with.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Horley: questions and answers
Do you work for managing agents with blocks near Banbury station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Will you take on work at estates like Alkerton Oaks Business Park, close to Horley?
Yes. We cover Horley and the area around it, including industrial estates, business parks and retail parks such as Alkerton Oaks Business Park. A few photos and the unit address let us price the work.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How do you handle work on occupied blocks?
The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Blocks and managed buildings in Horley
Horley is about 69 miles from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. Horley sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Trustees of buildings like Church of St Ethelreda can bring frame and external mastic into a planned maintenance list. Site managers at schools like North Oxfordshire Academy can fit frame mastic into the summer works.

Do you need mastic sealing in Horley?
Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified it comes away from one face.
Clients usually get in touch after noticing one or more of the following:
- Patchy repairs in mismatched sealant
- Estate-wide sealant that is simply worn out
- Movement joints with sealant missing
- Occupiers reporting cold air round windows
Property owners at sites such as Alkerton Oaks Business Park (2.4 miles west of Horley) can have mastic renewed between lettings.

Honest limits
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Leaks from above rather than through a joint
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly.

How the job changes by surface
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.
Estate-wide resealing programmes
Consistent products and colours across an estate make future maintenance simpler and easier to manage.

Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Have the asbestos survey to hand for older buildings
- Include mastic in your cyclical inspections
- Make it easy for occupiers to report draughts
- Share your contractor requirements early
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
