How the job changes by surface
Window and door perimeters
Gaps around frames have to be within the sealant’s range. Gaps outside the product’s range are raised with the site team.
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. Done properly, it saves decorators time and gives a clean line and keeps the snag list down.
Construction mastic in Brasted Chart, done properly
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. If you are dealing with a mastic package split between trades with no clear owner and a long mastic snag list close to completion, we can help. A specialist sealant contractor works differently from a general builder: on jobs in Brasted Chart, preparation and product choice get the time they need.
In the countryside around places like Brasted Chart, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

General trades versus a specialist
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.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Your questions answered
Do you take on work at healthcare sites like Tandridge Priory?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is Brasted Chart too small for you to travel to?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you come in just for snagging?
Yes, we can. Share the list and photographs, and a fixed quote follows, then clear it to your programme.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Are you CHAS accredited?
CHAS and Constructionline are both in place, and our applicators hold CSCS cards. Public liability insurance is in place.
How long does a typical visit take?
That varies with the scale of the job, but the work usually takes whatever the programme allows, since the work follows the trades as areas are released. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can staff carry on working while you are here?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. Smaller jobs around Brasted Chart can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.
- Drawings, the sealant specification and your programme come to us for pricing.
- We return a fixed quote that ties the mastic package to your programme.

Advice
Sites and facades in and around Brasted Chart
The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. Central London is about 18 miles from Brasted Chart. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
For a contractor working at a hospital such as Tandridge Priory, 3.3 miles to the west of Brasted Chart, perimeter and facade sealing is planned around patients and deliveries. Historic houses such as Quebec House, 1.2 miles west of Brasted Chart, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

What else we do in Brasted Chart
Do you need construction mastic in Brasted Chart?
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. We flag them early rather than filling them with sealant that won’t last.
Most enquiries start with something like this:
- Sanitary sealant damaged by following trades
- Early adhesion failures on new external joints
- Existing joints on a refurb that need cutting out and resealing
- Frame perimeters left unsealed or poorly sealed
New units and refits on sites such as Salters Heath Business Centre (to the east of Brasted Chart) need their panel and perimeter joints sealed to the specification.
Before you book anyone
- Their public liability cover
- Is the sealant right for the movement and the substrate?
- How the existing material will be dealt with
- Whether primer will be used where the manufacturer specifies it
Why deal with it now?
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects and external joints are where it shows first. Where an alternative is genuinely suitable, we will say so. For buildings around smaller places like Brasted Chart, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why appoint us
- CSCS-carded applicators
- A range of standard colours, depending on the product
- Colour agreed before work starts
- Matching to RAL references, product permitting

Cost factors for mastic packages
To price the job, we consider:
- Quantities, in metres or numbers
- Whether the work must be split into stages
- How much existing material needs removing
- Location, for remote and island sites
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What we need to price the job
Good information means a firmer quote. When you get in touch, include:
- The asbestos register, for older buildings
- The postcode of the building
- Approximate linear metres or a joint schedule
- Any specification or named product
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
