How commercial sealant contractors works in GU6
Mastic Doctor has been sealing joints for businesses and contractors since 2005: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. Site teams most often ask us about frame mastic that has hardened and come away from the wall and expansion joints with the sealant torn out, on external facade joints, movement joints in walls and floors and floor and threshold joints.
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Where parts of the building must stay open, the work is phased.
- Old sealant is cut out completely, never sealed over.
- Each joint gets a suitable sealant, laid to depth and tooled.
- We check the work with you, and the 12-month guarantee starts.
How we quote
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Commercial sealant contractors across GU6: the area picture
Commercial buildings across GU6 range from older premises altered many times to recent units on business parks. Surfaces decide the sealant, from masonry to powder-coated frames and shop-fit panels.
London and the South East are among the drier parts of the UK, but external sealing in GU6 still needs a dry joint and the right temperature, and damp or frosty mornings can hold it up.
Cranleigh: Occupiers with premises at both Littlemead Industrial Estate and Manfield Park Industrial Estate could have the sealant at each handled under one quote. For a hotel such as Ruffold Farm House Hotel, which lies west of Cranleigh, the colour of a joint at the bar or the bath matters to the look of the room.
Why it fails
Resealing over the top is a false economy we come across often. New silicone has nothing to key into so it soon peels and traps moisture against the joint. By the time it shows, there can be two or three layers to cut out.
Most enquiries start with something like this:
- Earlier reseals applied straight onto the failed bead
- Greasy, split joints in a kitchen or tea point
- Window and door perimeter joints that have cracked open
- Weathered facade sealant that no longer flexes
How the quote is worked out
We price every job individually. The things that drive the figure:
- Removal of failed or old sealant
- Location, for remote and island sites
- Site requirements such as inductions and permits
- Joint width, depth and condition
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.
Before you send an enquiry
Whether it’s one area or a whole building, these details speed things up:
- A wide shot and a close-up of the area
- Access details, including height
- The product your specification calls for
- Whether an asbestos survey exists
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, give us a call on 01277 525 020 or send details through our quote form.
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Faulty windows rather than failed perimeter sealant
- Suspect materials that need testing and specialist removal
- Leaks from pipework, wastes or valves (that’s plumbing)
Maintenance after handover
To get the most from the new sealant:
- Ask fit-out and M&E contractors to report any sealant they disturb
- Don’t let cleaning or traffic back on before the cure time is up
- Note dates and locations of sealant work for future planning
- Report cracked or peeling sealant early
Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records, and tell us if a joint we sealed gives trouble within that time.
A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.
Surface by surface
Washrooms and toilets
Mould that has grown into washroom sealant can’t normally be cleaned out. Replacement is the fix: strip, clean, dry and reseal.
Fire-rated seals where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps, so we will flag it if the detail needs a different product.
Questions about GU6
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can you handle sealant work across several sites?
Yes. We take on runs of jobs across portfolios as well as single sites, quoted per building or as a package.
Which site documents can you send us?
The paperwork is agreed with the quote: most clients ask for RAMS, our insurance certificate and CSCS details. Our applicators are CSCS-carded.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
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: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
