Coloured sealant for businesses in Gibraltar
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Our process
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Gibraltar are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- Photos or drawings show us the finishes and joints.
- Colour options from the specified product’s range are shared with you.
- The programme and access are agreed, including any phasing.
- Joints are prepared, primed where specified and backed.
- The agreed colour is installed and tooled neatly.
Before we start on site
- Confirm the product named in the specification
- Tell us which areas need to stay in use
- Send asbestos survey details if the building is pre-2000

Coloured sealant for commercial buildings in Gibraltar
Stone, brick and cladding each bring their own colour challenge: a stone or brick facade shifts in tone from one area to the next. The aim is a sealant colour that sits comfortably against the whole surface, with a sample on site if colour is critical. We work on powder-coated and anodised frames, cladding panels and office fit-out finishes, and the usual reasons a site gets in touch are discoloured joints on a visible elevation and hotel refurbishments with a set colour scheme. Searching for sealant specialists in Gibraltar? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
In and around smaller places such as Gibraltar, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Commercial premises in Gibraltar
Gibraltar sits in one of the drier corners of the country, the South East. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. At about 40 miles from central London, Gibraltar is within reach of the capital. The commuter belt holds a great many offices, retail parks and business parks. Multi-site occupiers here often want one sealant contractor across all their buildings.
On estates like Haddenham Industrial Park, which lies south-west of Gibraltar, the office and welfare end of each unit has its own sealant to maintain.
Gibraltar is about 3 miles south-west of Haydon Hill, in Buckinghamshire. We cover Gibraltar, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Gibraltar is one of 308 places we cover in Buckinghamshire for colour-matched joints. There’s a separate page for Oxford, roughly 14 miles from Gibraltar.
Commercial sites across HP17 and HP18 are covered. If your site is on New Road, Brogan Place and Donnington Row or close by, send details and we will quote for colour-matched joints. Sites close to Gibraltar are covered too, including Cuddington (1 mile west), Haddenham (2 miles south-west), Chearsley (2 miles west), Kingsey (3 miles south) and Towersey (4 miles south-west). Nearby towns on our patch include Aylesbury (4 miles north-east), High Wycombe (13 miles south-east), Chesham (14 miles south-east), Buckingham (15 miles north), Amersham (15 miles south-east) and Elmhurst (5 miles north-east).
Around Gibraltar
We work on buildings around The Seven Stars Public House, among other places. The closest station to Gibraltar is Haddenham & Thame Parkway station, about 2.2 miles south-west of the centre. Nearby you will also find St John's Hospital (1.4 miles north-east) and Dinton Castle (0.6 miles north-east). Not far away are Snakemoor.
Leave it or put it right?
It’s far cheaper to approve a sample than to strip and redo a full run. A sample takes little time. One visit to deal with every failing joint makes more sense than several trips to a place like Gibraltar. Send photos of each area and we’ll quote for the lot.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Cost factors for colour-matched joints
A fixed quote reflects the actual work. It allows for:
- The total length or number of joints
- The site’s rules and procedures
- Working within restricted access windows
- Access and working height
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- The asbestos register, for older buildings
- The type of building and who uses it
- Your programme or deadline
- Drawings or a marked-up plan, if available
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or email a schedule or drawings.
Do you need coloured sealant in Gibraltar?
Failed sealant still has to be dealt with, whatever its colour: splits, adhesion loss and hardening all happen. The fix is a full cut-out and a new bead in the right colour.
Site and facilities staff are often the first to spot these:
- Standard-colour sealant spoiling a high-end finish
- Fit-outs with a sealant colour in the specification
- Coloured joints that have cracked with movement
- Weathered sealant that no longer matches
For premises near Haddenham & Thame Parkway station, which lies south-west of Gibraltar, footfall is part of the plan: work is phased so shops and offices keep trading.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- Will failed sealant be removed rather than covered?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Is the sealant right for the movement and the substrate?
For managing agents and facilities managers
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
FAQs: Gibraltar
Can the sealant on our Gibraltar premises match the finishes?
Yes, we can typically get close to most finishes from the product’s colour range. Send colour references or photos and we will confirm what’s available for the product.
Is Haddenham Industrial Park, near Gibraltar, within your area?
Yes. Estates, retail parks and business parks around Gibraltar, Haddenham Industrial Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
How long does a job like this take?
It depends on the scope, but the work normally takes a day for a modest shop fit, and longer for a full building or several floors. For bigger or phased jobs, we will set out a timescale with the quote.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

What else we do in Gibraltar
Surface by surface
Natural stone
Natural stone rarely has one colour, and the sealant has to work with that. A stone-compatible, neutral-cure sealant avoids staining in the closest available colour.
Brick and masonry
Movement joints in brickwork are long and visible. The right colour keeps them discreet without affecting the joint’s performance.
