Common questions from Markbeech clients
Can you keep pace with our programme in Markbeech?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is Markbeech off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Can fire-rated sealing at service penetrations be included?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. The design and sign-off belong to the designer, fire engineer or building control.
Are you CHAS accredited?
Our applicators hold CSCS cards, and we’re CHAS accredited and a Constructionline member. We’re also fully insured, with five million pounds of public liability cover.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Construction mastic in Markbeech
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. Site teams most often ask us about oversized or tapered gaps around new frames and early adhesion failures on new external joints, on sanitary and kitchen joints, window and door perimeters and floor and skirting junctions. Looking for mastic applicators who cover Markbeech? We’ve been sealing commercial buildings since 2005.
Around smaller places like Markbeech, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

How the job changes by surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly.
Window and door perimeters
Internal perimeters are usually sealed with a paintable product where decorating follows. The specification decides which, and colour-matched products can be used where the frame is on show.
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Check frame gaps are within the sealant’s range before sealing
- Put any product change through the designer first
- Ask for joint and product checks before the package is urgent
- Don’t force external sealing on a damp or frosty day
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby.
A missed perimeter seal on one window can wet the reveal and the plaster inside. That normally means redoing finishes in a completed area and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.
Other services in Markbeech
Work for main contractors and building owners
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Leave it or put it right?
Patching snags as they appear can feel quicker than a proper close-out. But one planned snagging pass through each area normally clears more for less disruption. We can run snagging as its own phase before handover. One visit to deal with every failing joint makes more sense than several trips to a place like Markbeech, rather than one at a time. Send photos of each area and we will quote for the lot.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

Signs you need construction mastic in Markbeech
Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, and the joint has to be redone.
Most enquiries start with one or more of the following:
- Perimeter gaps outside the sealant’s range
- Different trades sealing to different standards
- Early adhesion failures on new external joints
- Old sealant on a refurbishment that needs stripping before new work
On a healthcare site such as Edenbridge and District War Memorial Hospital (2.4 miles north-west of Markbeech), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What to look for in a quote
- Will failed sealant be removed rather than covered?
- What level of public liability insurance do they hold?
- Who will actually carry out the work
- The terms of the workmanship guarantee
