Mastic sealing in Farnham
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on shopfronts below residential blocks, window and door perimeters on blocks and balcony and threshold joints, and the failures we’re asked to look at most are water getting in round frames after rain and draught complaints from residents or tenants. A specialist sealant contractor works differently from a general builder: on jobs in Farnham, preparation and product choice get the time they need.
For buildings around smaller places like Farnham, we group work so one trip covers it. Send photographs of the frames and joints and we’ll give a fixed quote.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Our process
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Farnham are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
What we need from you
- Arrange parking or a loading space
- Move anything stored against the joints

What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Materials that need asbestos testing before work
- Leaks through the frame itself rather than the perimeter
If you are not sure, just phone 01277 525 020 or send photos by email and we will give you a straight answer before you book.
Joints and surfaces we work on
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- External wall and movement joints
- Balcony and threshold joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
Different surfaces, different methods
Window and door perimeters on blocks
Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.
Tenement and older buildings
Natural stone can be marked by the wrong sealant, so we pick a grade that won’t mark it.
Keeping the joints sound
A few simple habits keep the new joints working:
- Check sealant joints during planned building inspections
- Track which buildings were done and when
- Protect low-level joints in entrances
- Prioritise elevations facing the weather
If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, routine checks spot the next round of repairs.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
Questions we’re asked in Farnham
Do you work for managing agents with blocks near Stansted Mountfitchet station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Can you work at a site such as Birchanger Industrial Estate, by Farnham?
Yes. We cover Farnham and the area around it, including industrial estates, business parks and retail parks such as Birchanger Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
Can you seal joints high up on a block?
It depends on the building. We agree access with you at quote stage so there are no surprises.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Can you reseal a whole block or estate?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
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 entrances stay in use.

How the quote is worked out
These are the things that shape the price:
- Removal of failed or old sealant
- Whether the work must be split into stages
- The site’s rules and procedures
- The product specified
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What we need to price the job
A few photographs plus some basic facts will normally do. Please tell us:
- Clear photographs of the problem areas
- The postcode of the building
- Specification clauses that apply
- How the joints are reached, and at what height
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or use the quote form to discuss it first.
General trades versus a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
