Construction mastic for commercial buildings in Fleet
Mastic follows everyone else, which means it absorbs every delay upstream. The sequence is set with the site team and updated as plots or floors are handed over, so applicators arrive when areas are genuinely ready. Sealing too early only means coming back once others have damaged it. We work on floor and skirting junctions, cladding and panel joints and window and door perimeters, and what we are called in for most is oversized or tapered gaps around new frames and frame perimeters left unsealed or poorly sealed. Whoever orders the work in Fleet, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In towns like Fleet, sites are usually modest: small housing schemes, extensions to schools and surgeries, refurbished shops and offices. A mastic package on a smaller site still needs the same care at window perimeters and facade joints.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Why act early in Fleet
A cheaper sealant can look like an easy saving on a large package. A failed joint in the defects period costs far more than the product difference, especially externally. Where an alternative is genuinely suitable, we’ll say so. A failed joint is easier to put right before damp shows inside. Once water gets in, there’s drying out and making good as well.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Surface by surface
External facade and movement joints
External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it and work only when conditions suit.
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move, and we use a flexible sealant where there’s movement.

Our process
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. If you have more than one building in Fleet, they can often be done on the same visit, with one quote covering them. Give us your access times and we’ll fit the work in.
- Drawings, the sealant specification and your programme come to us for pricing.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- We seal each plot or floor as it’s released to us.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Preparing the site
- Point out parking and an unloading spot
- Let us know about inductions and permits
- Tell staff and tenants when we will be in

Advice
Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Construction mastic around Fleet: what changes locally
Fleet is about 36 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. Rainfall across the South East, Fleet included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.
University estates such as University for the Creative Arts, 4.2 miles south of Fleet, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Hospital estates such as Fleet Community Hospital (to the north-west of Fleet) 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.
Fleet is about 13 miles south-east of Reading, in Hampshire. We send applicators to Fleet for mastic packages, handled exactly as we handle every other area. Our Hampshire coverage takes in 723 places, large and small. Reading is covered too, some 13 miles away.

Common problems we fix in Fleet
On a live site, contamination is the biggest threat to a new joint. Plaster dust, release agents, protective film residue and damp all stop sealant bonding.
If one of these sounds familiar, it’s time for a closer look:
- Bath and shower joints scraped during the final clean
- Existing joints on a refurb that need cutting out and resealing
- Frame gaps too wide for sealant alone
- A long mastic snag list close to completion
School extensions, at buildings such as Heatherside Junior School, typically run to the summer holidays, mastic included.

What affects the price in Fleet
There’s no standard rate for sealant work, because every site is different. What we look at:
- Any access equipment needed
- Phasing around occupants
- Removal of failed or old sealant
- Backing rod, priming and other preparation
We don’t publish prices, 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.
What we need to price the job
However big the job, the same details help:
- Any dates the work must fit around
- Photos of the joints, close up and from further back
- Whether an asbestos survey exists
- Specification clauses that apply
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
