Maintenance after handover
Regular inspection catches problems early. Specifically:
- Plan racking layouts so feet don’t land on a joint
- Keep traffic off new joints until the cure time is up
- Keep stones and debris out of open joint lines
- Put movement joints on the planned maintenance inspection round
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Resealing promptly prevents internal damage.
About our expansion joint sealing in Gibraltar
We have been sealing expansion and movement joints for over 20 years, for main contractors, FMs, managing agents and building owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on blockwork control joints, precast concrete panel joints and cladding panel joints, and what we’re called in for most is sealant pulling off the joint face and expansion joints split through the centre of the bead. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Gibraltar is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In and around smaller places like Gibraltar, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Expansion joint sealing around Gibraltar: what changes locally
Rainfall across the South East, Gibraltar included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. Central London is about 40 miles from Gibraltar. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.
For estates staff at a university like University Campus Aylesbury Vale, 4.3 miles to the east of Gibraltar, building and paving joints are part of the planned maintenance list. On industrial estates such as Haddenham Industrial Park, 1.7 miles south-west of Gibraltar, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Hospitals like St John's Hospital, 1.4 miles north-east of Gibraltar, have multi-storey or surface car parks whose joints carry vehicles round the clock.
Gibraltar is about 3 miles south-west of Haydon Hill, in Buckinghamshire. Commercial clients in Gibraltar use us for work on movement joints, as part of our coverage of Buckinghamshire. We work across 308 places in Buckinghamshire. For work in that direction, see our Oxford page (14 miles or so).
Postcode districts covered here: HP17 and HP18. For a building on New Road, Brogan Place and Donnington Row or nearby, we can quote for movement joints. Close to Gibraltar, our area also takes in Cuddington (1 mile west), Haddenham (2 miles south-west), Chearsley (2 miles west), Kingsey (3 miles south) and Towersey (4 miles south-west).

Gibraltar: questions and answers
Would you work within a site like St John's Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you cover business parks and estates near Gibraltar, such as Haddenham Industrial Park?
Yes. Estates, retail parks and business parks around Gibraltar, Haddenham Industrial Park among them, are all within reach. A few photographs and the unit address let us price the work.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, which many sites require.
What timescale should we allow for resealing expansion joints?
It usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. We confirm the timescale with the quote, including any phasing.
What exactly is a movement joint?
They’re closely related. A movement joint allows for expansion, contraction, shrinkage and loading, and the seal across it keeps water and debris out.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Building owners, agents and FMs in Gibraltar
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

What sets the cost
We price every job individually. The things that drive the figure:
- The site’s rules and procedures
- Which sealant the job calls for
- Whether old sealant has to be cut out first
- Distance, for remote addresses
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
Details that help us quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Where the site is, with the postcode
- Whether an asbestos survey exists
- Whether the building will be occupied during the work
- Photos of the joints, close up and from further back
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
Diagnose, treat, sign off
Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Gibraltar are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
Before we start on site
- Point out any areas we must not close
- Share your working hours and any access restrictions
- Move anything stored against the joints

Advice
Why act early in Gibraltar
Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed and we’ll tell you honestly. For buildings around smaller places like Gibraltar, 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.
A quote for movement joints depends on quantities, condition and access. Ask us for a fixed quote.
