Construction mastic across Cranleigh
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
How the quote is worked out
The price varies from site to site. It mainly depends on:
- Quantities, in metres or numbers
- Whether old sealant has to be cut out first
- Whether the work must be split into stages
- Any access equipment needed
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- Whether the building will be occupied during the work
- Any specification or named product
- Approximate linear metres or a joint schedule
- How the joints are reached, and at what height
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
How we handle construction mastic in Cranleigh
Site managers want applicators who turn up with the right cards and paperwork. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, with public liability insurance in place. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. If you have sealant knocked or painted over by other trades and oversized or tapered gaps around new frames, we can put it right, on window and door perimeters, sanitary and kitchen joints and floor and skirting junctions alike. Searching for sealant specialists in Cranleigh? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Conversions around smaller places like Cranleigh often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Surface by surface
External facade and movement joints
Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it, and seal only with a dry joint inside the product’s temperature range.
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move, and we use a flexible sealant where there’s movement.
New build and refits around Cranleigh
Rainfall across the South East, Cranleigh included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. Cranleigh is about 30 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.
Hotels like Ruffold Farm House Hotel, 1.2 miles to the west of Cranleigh, rarely close for long, so refurbishment mastic is phased floor by floor. For contractors refurbishing units at places like Littlemead Industrial Estate, 1 mile west of Cranleigh, the mastic covers cladding panels, roller-door and window perimeters.
Cranleigh is about 8 miles south-east of Guildford, in Surrey. Anywhere in GU6, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Surrey coverage takes in 379 places. We also cover Brighton, around 26 miles from Cranleigh.
Postcode districts covered here: GU6 for mastic packages. For a building on High Street, Taverner Square and Bridge Road or nearby, we can quote for mastic packages.

Common questions from Cranleigh clients
Will you fit the mastic around our build programme in Cranleigh?
Yes. The mastic is planned around your key stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Cranleigh too small for you to travel to?
Not at all. Cranleigh is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
How do I request a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we’ll price it properly.
Can you work while the building is occupied?
In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Looking after the joints
For the best life from the joints:
- Keep scrapers and abrasive pads off new beads
- Get the mastic subcontractor involved early in the programme
- Brief following trades on areas that have been sealed
- Don’t force external sealing on a damp or frosty day
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later, and tells you what to reseal with. We can confirm the handover information you need when we quote.
Snag items left to the last week put handover at risk. A planned close-out through each area as it completes keeps the list short, and avoids a rush.
On site: what to expect
The first thing on site is a walk round with your contact, 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. What matters most for a job in Cranleigh is a clear list of what needs doing. A fixed quote follows.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Share your working hours and any access restrictions
- Warn occupants and staff about the work
- Arrange parking or a loading space
Getting a fixed quote
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Advice
When to call us in Cranleigh
A new building moves while it dries and settles. Materials lose construction moisture and shrink, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.
These are often picked up first by site or facilities staff:
- Caulk cracking where joints are moving more than expected
- Perimeter gaps outside the sealant’s range
- Early adhesion failures on new external joints
- Different trades sealing to different standards
For contractors at a school such as St Cuthbert Mayne Catholic Primary School, sealing has to be finished before term starts.
Comparing quotes
- Will RAMS and insurance details be available?
- How the joint faces will be prepared and primed
- Their plan for phasing and protecting the area
- Whether their applicators hold CSCS cards
Why act early in Cranleigh
Some packages split mastic across the window fitter, kitchen fitter and plumber. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility and a consistent finish. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
Pricing mastic packages depends on quantities, condition and access. Ask us for a fixed quote.
