Construction mastic in Preston
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone, and on older buildings we ask for the asbestos survey before disturbing anything. New and existing joints then get the same preparation. If you are dealing with oversized or tapered gaps around new frames and sealant knocked or painted over by other trades, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Preston is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around places like Preston, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Work in places the size of Preston is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- 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.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Confirm the product named in the specification
- Point out parking and an unloading spot
- Tell us which areas need to stay in use

Advice
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Redoing a failed joint typically costs more than getting it right at the outset, 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.
Cost factors for mastic packages
Your fixed quote is built from the real scope. It takes account of:
- Location, for remote and island sites
- Whether old sealant has to be cut out first
- Working within restricted access windows
- Joint width, depth and condition
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Details that help us quote
For an accurate fixed quote, we need to understand the site. Useful things to include:
- The product your specification calls for
- Access details, including height
- Whether an asbestos survey exists
- Rough lengths or quantities, or drawings if you have them
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or use the quote form.
For managing agents and facilities managers
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Preston. One quote can cover more than one site, so there’s one set of paperwork to deal with.
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.
New build and refits around Preston
Preston lies within about 2 miles of the sea. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so we check the specified product suits the exposure before the first bead. Central London is about 45 miles from Preston. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.
Further education sites such as Varndean College (0.5 miles north-east of Preston) are extended and refurbished from time to time, with mastic often programmed into the summer break. For contractors on a campus like University of Brighton Moulesecoomb Campus, which lies east of Preston, facade and perimeter sealing has to fit around students and term dates.

Your questions answered
Does the sea air around Preston change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Is a smaller place like Preston outside your area?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Is the mastic package guaranteed?
It carries a 12-month guarantee on our workmanship. We carry five million pounds of public liability insurance.
Do you do fire-rated sealing on new builds?
Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. The design and sign-off belong to the designer, fire engineer or building control.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Signs you need construction mastic in Preston
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond.
What tends to prompt an enquiry:
- Early adhesion failures on new external joints
- Cracks opening in caulked internal joints
- Mastic snags holding up handover
- Perimeter gaps outside the sealant’s range
Hospital estates such as The Montefiore Hospital (to the south of Preston) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
What your quote should include
- Health and safety accreditation such as CHAS
- Will failed sealant be removed rather than covered?
- Will RAMS and insurance details be available?
- The named product and why it was chosen
Why it’s worth doing now in Preston
It helps to bring the mastic subcontractor in before the package is urgent. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification. Called in at the end, the same issues surface during handover. In a smaller place such as Preston, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
