Photos, a specification or a quick description of the joints is enough to start a fixed quote.
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
About our construction mastic in Dibden
The specification and the programme set the job. If a product is named, that’s what goes in. Joint widths, backing, primers and tooling follow the manufacturer’s guidance so the detail on the drawing is what ends up on site. The enquiries we see most involve failed sealant in an existing building being refurbished and early adhesion failures on new external joints, across floor and skirting junctions, cladding and panel joints and internal decorators’ caulk. A specialist sealant contractor works differently from a general builder: on jobs in Dibden, preparation and product choice get the time they need.
For a contractor on a smaller site near Dibden, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Our process
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. What matters most for a job in Dibden is a clear list of what needs doing. You will then get a fixed price for the work.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised straight away.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Make sure the joints can be reached
- Tell us what induction or permit system the site runs
- Tell staff and tenants when we’ll be in
Getting a fixed quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Advice
Surface by surface
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area, cutting out damaged joints and resealing them properly.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Frames fitted out of tolerance
- Glazing units that are cracked or misted
- Specifying the product where the designer hasn’t
If you are not sure, just ring 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

Questions we’re asked in Dibden
Is Dibden too far out for you?
Not at all. Dibden is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Our building in Dibden is near the coast: does that change the sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Signs you need construction mastic in Dibden
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. Better to raise it at the start than seal a joint that’s bound to fail.
Common reasons buildings call us in:
- Existing joints on a refurb that need cutting out and resealing
- Sealant knocked or painted over by other trades
- Mastic snags holding up handover
- Cracks opening in caulked internal joints
When units on a site such as Hardley Industrial Estate (2.1 miles south-east of Dibden) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Construction mastic around Dibden: what changes locally
Dibden lies within about 2 miles of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.
For a contractor working at a hospital such as Hythe Hospital, which lies south-east of Dibden, perimeter and facade sealing is planned around patients and deliveries. Projects at schools like Applemore College work to term dates, so mastic is programmed tightly.
Dibden is about 1 mile west of Hythe, in Hampshire. We cover Dibden and the rest of Hampshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Dibden is one of 723 places in Hampshire on our list for mastic packages.
If you need construction mastic in SO45, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on Cavalier Close, Cathay Gardens and Canterbury Drive are within our area for mastic packages. Sites close to Dibden are covered too, including Dibden Purlieu (1 mile south-east), Hythe (1 mile east), Marchwood (2 miles north-west), Beaulieu (3 miles south) and The Hummicks (4 miles south). Nearby towns on our patch include Winchester (14 miles north), Gosport (13 miles east), Eastleigh (8 miles north-east), Fareham (10 miles east), Totton (5 miles north-west) and Chandler's Ford (8 miles north).
Landmarks near Dibden
We work on buildings around Testwood School and Orchard Junior School. The closest station to Dibden is Southampton Town Quay station, roughly 2.2 miles north-east of the centre. Well-known places in the area include Royal South Hants Hospital (3.5 miles north) and Westquay (2.8 miles north).
Keeping the joints sound
To get the most from the new sealant:
- Don’t schedule sealing before decorators and flooring are done
- Stick to the specified sealant rather than a generic substitute
- Ask installers to correct oversized gaps first
- Keep finished joints away from paint, plaster and scrapers
Any damage after we have finished should go on the snag list straight away. We can return to clear snags before handover as agreed in the quote.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.
