How the quote is worked out
These are the things that shape the price:
- Induction, permit and paperwork requirements

- Any access equipment needed
- Removal of failed or old sealant
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.

To price the job accurately, we need to understand the site. Send us:
- Drawings or a marked-up plan, if available
- Any dates the work must fit around
- Whether the building will be occupied during the work
- The site address and postcode
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or email a schedule or drawings.
Mastic sealing in Prestonville, done properly
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. If you have a mix of products and colours from past repairs and the same joint failures repeated across a portfolio, we can put it right, whatever the surface. Most enquiries from Prestonville 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.
Owners with buildings around smaller places like Prestonville often group mastic work so one visit covers several properties. One quote can cover a whole list of addresses.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Blocks and managed buildings in Prestonville
Prestonville lies within about 1 mile of the sea. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do. Prestonville sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
If you manage student housing near a university such as University of Brighton Moulesecoomb Campus, 1.5 miles to the east of Prestonville, the summer turnaround is the time for mastic. Schools and community buildings such as Stanford Infant School need frame and external mastic kept sound like any building. Blocks of flats and mixed-use buildings often cluster around stations such as Preston Park station (to the north of Prestonville) and their window and balcony mastic tends to age at the same rate across a building.
Prestonville is about 1 mile west of Brighton, in Brighton and Hove. If you are looking for mastic sealing in Prestonville, we can help. Prestonville is one of 29 places in Brighton and Hove on our list.

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Materials that need asbestos testing before work
- Frames that are rotten, warped or broken
- Water coming in from the roof or rainwater goods
Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly before you book.
Joints and surfaces we work on
- External wall and movement joints
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Balcony and threshold joints
Our process
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. Work in places the size of Prestonville is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Tell us your opening times and when work is allowed
- Send asbestos survey details if the building is pre-2000
- Flag any permit to work we’ll need
Getting a fixed quote
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Related advice
Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Group repairs into a planned programme
- List the paperwork your organisation requires when you send details
- Protect low-level joints in entrances
- Make it easy for occupiers to report draughts
Keep records of when each building was resealed. It helps plan the next round and gives you a history.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.
Building owners, agents and FMs in Prestonville
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, with each stage agreed with your site contact.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Prestonville can sit alongside others in a wider programme.
FAQs: Prestonville
Can you work in a care home near Prestonville with residents in?
Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.
Is Centenary Industrial Estate, near Prestonville, within your area?
Yes. Our area takes in Prestonville and its surroundings, with estates and business parks such as Centenary Industrial Estate included. Photos and a short description are enough for a first look.
Can you send RAMS and CSCS details before starting?
Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you work for managing agents and housing associations?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
How long does a typical visit take?
It depends on the scope, but the work usually takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
