How a job runs
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Smaller jobs around Crofton can be grouped with others nearby. A fixed quote is given before anything starts.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.

Related advice
Do you need mastic sealing in Crofton?
Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.
If one of these sounds familiar, it’s time for a closer look:
- The same joint failures repeated across a portfolio
- Patchy repairs in mismatched sealant
- Water getting in round frames after rain
- Failed external movement joints
Student blocks close to universities like University of Portsmouth - North Zone (to the east of Crofton) are easiest to work on between tenancies.
What your quote should include
- Which product they’ll use, and why it suits the joint
- What level of public liability insurance do they hold?
- Health and safety accreditation such as CHAS
- Do they follow the manufacturer’s priming guidance?

After the work
For the best life from the joints:
- List the paperwork your organisation requires when you send details
- Reduce knocks to communal area joints
- Log resealing dates block by block
- Encourage occupiers to report problems at frames
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
One failed perimeter usually means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.
General trades versus a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Frames, entrances and external joints in Crofton
Crofton sits close to the coast, within about 1 mile. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first; plan inspections around that. At about 67 miles from central London, Crofton is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations.
Churches, halls and community buildings such as Peel Common Mission Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. If your remit includes a building such as Crofton School, frame and door mastic can be programmed for the holidays.

FAQs: Crofton
We manage a building near Fareham station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Is Crofton off your patch?
No. Places such as Crofton are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.
Can you plan resealing across several buildings?
We can. We survey and price each building, then work through them in order starting wherever is most urgent.
Which sealant will you use?
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.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Will you just go over the old 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.
Commercial clients in Crofton
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
What affects the price in Crofton
Quotes vary with the job. It mainly depends on:
- Travel to remote or island sites
- How much there is to seal
- Whether the work must be split into stages
- Backing rod, priming and other preparation
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- Access details, including height
- Your programme or deadline
- Whether an asbestos survey exists
- The type of building and who uses it
