What we can’t put right
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Misted, cracked or failed glazing units (a glazier’s job)
- A dripping trap, valve or pipe behind a fitting
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think.
What we seal
- Movement joints in walls and floors
- External facade joints
- Window and door perimeters
- Kitchen worktops and splashbacks
- Floor and threshold joints
- Washrooms and tea points
How we handle commercial sealant contractors in Twelve Oaks
On a commercial site, sealant turns up in more places than people expect: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Externally it keeps rain out of frame perimeters, panel joints and movement joints. Our applicators work on both the inside and the outside of the building. We work on kitchen worktops and splashbacks, window and door perimeters and floor and threshold joints, and the failures we are asked to look at most are hardened, chalky sealant on south-facing or exposed elevations and mouldy silicone around WCs, urinals and vanity tops. Most enquiries from Twelve Oaks start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Quotes for commercial sealant in Twelve Oaks can come from photographs and a joint schedule, or from a walk-round, and the scope is set out in writing.
Rural business units near smaller places such as Twelve Oaks are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.
Every job we finish is backed by a 12-month workmanship guarantee, in Twelve Oaks as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What Twelve Oaks’s businesses ask us to seal
At about 43 miles from central London, Twelve Oaks is within reach of the capital. This part of the South East is dense with business parks and out-of-town offices. Firms with branches across the South East can use one contractor for every site. Twelve Oaks is in the South East, one of the UK’s drier regions. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.
For any commercial premises in Twelve Oaks, a lasting joint depends on full removal of the old sealant and clean, dry faces. Shops and cafés around stations like Robertsbridge station (3.4 miles north-east of Twelve Oaks) trade from early, so work is timed around them.

FAQs: Twelve Oaks
What documents will you need to give us for a job in Twelve Oaks?
We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Is Twelve Oaks too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How many days will you need on site?
It depends on the scope, though a typical visit usually takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. For bigger or phased jobs, we’ll set out a timescale with the quote.
What guarantee do you give on resealing?
A 12-month guarantee covers the workmanship. Looking after the joints as we advise helps them last.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Do you work for facilities managers and managing agents?
Yes. Use our quote form to send the site details, or phone or email us, and tell us what site paperwork you need.
Keeping the joints sound
To get the most from the new sealant:
- Make sure contractors see the asbestos survey before cutting out old mastic
- Report cracked or peeling sealant early
- Look at the sealant around anything that has been moved or replaced
- Keep a record of which joints were resealed and when
Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.
A failed external joint lets water in every time it rains. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Resealing early keeps the problem in the sealant and out of the building.
Building owners, agents and FMs in Twelve Oaks
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Smaller jobs around Twelve Oaks can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First, details come to us: photographs, drawings or a schedule of the areas, or we arrange a site visit.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Site hours, access windows and the order of areas are agreed before we start.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Finished joints are checked with you and handed over with our 12-month guarantee.
What we need from you
- Let us know about inductions and permits
- Make sure the joints can be reached
- Agree which areas must stay open

Advice
Why deal with it now?
Some low prices are low because nothing gets cut out. Sealing over looks tidy at handover, then lifts once the joint starts moving. Every quote we give includes full removal and preparation. Converted and older buildings near places like Twelve Oaks tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Why appoint us
- Colours confirmed for the specified product
- Public liability insurance in place
- Failed material removed, not covered up
- One number for every site we cover

When to bring in a specialist
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
