Construction mastic for commercial buildings in The Hummicks
Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. Most enquiries involve mastic snags holding up handover and old sealant on a refurbishment that needs stripping before new work, on floor and skirting junctions, cladding and panel joints and internal decorators’ caulk. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in The Hummicks, preparation and product choice get the time they need.
Construction in and around smaller places such as The Hummicks is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common problems we fix in The Hummicks
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.
Any of the following is a good reason to get the joints checked over:
- Oversized or tapered gaps around new frames
- Internal caulk splitting as the building dries out
- Early adhesion failures on new external joints
- Different trades sealing to different standards
When a school such as Beaulieu Village Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Common questions from The Hummicks clients
Will you plan work around the academic year at somewhere like Totton College Waterside Centre?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you take on work at healthcare sites like Lymington New Forest Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
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. Fire-stopping design and sign-off sit with the designer and building control.
How many days will you need on site?
That varies with the scale of the job, but the work usually takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
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.

When it isn’t the sealant
Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:
- Joint design decisions that belong to the architect or engineer
- Damage to finishes by other trades after we have sealed
- Glazing units that are cracked or misted
Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly before you book.
What we seal
- Cladding and panel joints
- Sanitary and kitchen joints
- Floor and skirting junctions
- Brick and block movement joints
- Internal decorators’ caulk
- Window and door perimeters
How a job runs
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Rural sites near The Hummicks may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- 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.
What we need from you
- Have the specification and drawings to hand
- Explain the parking and delivery arrangements
- Let us know about inductions and permits

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Advice
Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Flag uneven or tapered frame gaps early
- Bring the mastic contractor in after the last trades are through
- Brief the final clean team to avoid blades near sealant
- Record the products used in the O&M file
Expect some settlement in the first months. Flexible sealants in the right joints handle normal movement, but caulk in a joint that moves more than expected may crack. If that happens, let us know.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels, and the repair falls into the defects period. Proper preparation, with the right silicone first time, keeps it off the defects list.
General trades versus a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Contractors’ notes for The Hummicks
The Hummicks sits close to the coast, within about 2 miles. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.
New wings at hospitals like Lymington New Forest Hospital (to the south-west of The Hummicks) bring long runs of window and panel joints to seal. For contractors at a college like Totton College Waterside Centre (2.7 miles north of The Hummicks), perimeters and internal sealant are timed for the holidays.
The Hummicks is about 4 miles south-west of Hythe, in Hampshire. Any commercial site in The Hummicks is covered, for single jobs and planned programmes alike. We work across 723 places in Hampshire. For work in that direction, see our Southampton page (7 miles or so).

What sets the cost
These are the things that shape the price:
- The size and state of each joint
- Whether old sealant has to be cut out first
- The site’s rules and procedures
- Phasing around occupants
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
