West Clandon: questions and answers
We manage a building near Clandon station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Will you take on work at estates like Merrow Business Park, close to West Clandon?
Yes. Estates, retail parks and business parks around West Clandon, Merrow Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Do you supply RAMS and insurance details?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Is West Clandon in your area?
Yes. We cover West Clandon, and the simplest way to start is to call 01277 525 020 or use the quote form.
Do you check for asbestos in old sealant?
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.
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 we handle mastic sealing in West Clandon
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on balcony and threshold joints, external wall and movement joints and communal kitchens and washrooms, and the failures we are asked to look at most are occupiers reporting cold air round windows and damp patches beside frames. Whether you call it commercial sealant work, mastic application or joint sealing, in West Clandon it comes down to the same thing: the right product in a properly prepared joint.
Owners and agents with buildings around smaller places such as West Clandon tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
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.

Diagnose, treat, sign off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like West Clandon are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- 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 sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Preparing the site
- Have the specification and drawings to hand
- Tell us which areas need to stay in use

More services for West Clandon
Work for main contractors and building owners
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.
Should maintenance staff do it?
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, which is what makes a joint last.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Different surfaces, different methods
Commercial and mixed-use buildings
Commercial occupiers typically stay open during the work so the work is phased.
Estate-wide resealing programmes
Priority order can follow condition, complaints or your maintenance plan. Quotes can be per block or for the full programme.
What we’re called out for in West Clandon
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
If one of these sounds familiar, it’s time for a closer look:
- Cracked, hardened mastic round windows on a block
- Leaks at window and door perimeters
- Old repairs sealed over failed mastic
- Draughts at frames across a block
If your remit includes a building such as Clandon CofE Aided Primary School, frame and door mastic can be programmed for the holidays.
Questions to ask before you book
- How the joint faces will be prepared and primed
- Can the work be phased to keep areas open?
- Whether their applicators hold CSCS cards
- Their pre-qualification and accreditations
Planned mastic for West Clandon portfolios
Rainfall across the South East, West Clandon included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building typically need attention first. West Clandon is about 24 miles from central London. Managed blocks of flats are a big part of commuter-belt property.
Blocks of flats and mixed-use buildings often cluster around stations such as Clandon station, under half a mile to the south of West Clandon, and their window and balcony mastic tends to age at the same rate across a building. If you are responsible for a building such as Church of St Peter and St Paul, frame and door mastic needs the same attention as any other property.

When something else is needed
Being straight saves everyone time. New sealant won’t cure:
- Leaks from above rather than through a joint
