Mastic sealing for commercial buildings in Headley Down
Managing agents and housing associations normally need paperwork before anyone starts. 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, with public liability insurance. We work on window and door perimeters on blocks, balcony and threshold joints and communal entrances and stairwells, and the usual reasons a site gets in touch are brittle perimeter mastic across a building and draughts at frames across a block. Whoever orders the work in Headley Down, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
In a smaller place such as Headley Down, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Questions about Headley Down
Do you work for managing agents with blocks near Liphook station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
Is Passfield Industrial Estate, near Headley Down, within your area?
Yes. We cover Headley Down and the area around it, including industrial estates, business parks and retail parks such as Passfield Industrial Estate. Photos and a short description are enough for a first look.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Will residents or tenants be disturbed?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
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 hold CHAS accreditation and Constructionline membership.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How the quote is worked out
Each job is priced on its own details. The things that drive the figure:
- Whether the work must be split into stages
- How accessible the joints are
- How much existing material needs removing
- Distance, for remote addresses
A quote for mastic joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.
Sending details for a quote
A good diagnosis starts with the right details. Let us know:
- How the joints are reached, and at what height
- Photos of the joints, close up and from further back
- Drawings or a marked-up plan, if available
- Whether an asbestos survey exists
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to phone 01277 525 020 or email the details over.
Why deal with it now?
Failed perimeter mastic lets cold air in around frames and the windows normally get the blame. Resealing the perimeters is often the simpler fix when the frames themselves are sound. In a smaller place such as Headley Down, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What else we do in Headley Down
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. 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.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Different surfaces, different methods
External movement joints
The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.
Estate-wide resealing programmes
Using the same products throughout keeps the estate consistent.
For owners and agents in Headley Down
Headley Down sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Headley Down lies roughly 40 miles out from central London. Managed blocks of flats are a big part of commuter-belt property.
Site managers at schools like The Holme Church of England Primary School can fit frame mastic into the summer works. Property owners at sites such as Passfield Industrial Estate (to the south-west of Headley Down) can have mastic renewed between lettings. Trustees of buildings like Church of All Saints can bring frame and external mastic into a planned maintenance list.
