Construction mastic for commercial buildings in Farnborough
Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. To price a package in Farnborough, send drawings and the specification through our quote form. The enquiries we see most involve different trades sealing to different standards and internal caulk splitting as the building dries out, on floor and skirting junctions, window and door perimeters and sanitary and kitchen joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Farnborough, that means joint design, primers and backing rod as standard.
Every London site, Farnborough included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What we are called out for in Farnborough
A joint without backing rod or bond-breaker often fails early. Fixed to three faces, the sealant rips the first time the joint opens.
Things that typically lead to an enquiry:
- Inconsistent sealant finishes from plot to plot
- Mastic snags holding up handover
- Internal caulk splitting as the building dries out
- Sealant knocked or painted over by other trades
Projects at schools like Farnborough Primary School work to term dates, so mastic is programmed tightly.

FAQs: Farnborough
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for
Is hospital work, at somewhere like Princess Royal University Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Does weather affect external mastic work?
Weather matters for external sealing: each sealant has a temperature range, and the joint must be dry. We plan external elevations with that in mind.
Can you work plot by plot or floor by floor?
Working to your programme, we seal each area as it’s handed over. The sequence is settled with your site team and adjusted as things change.
How many days will you need on site?
It depends on the scope, though a typical visit normally takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. For bigger or phased jobs, we will set out a timescale with the quote.
Can you work while the building is occupied?
In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Diagnose, treat, sign off
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.

What else we do in Farnborough
What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Phasing around occupants
- Site requirements such as inductions and permits
- Joint width, depth and condition
- How much existing material needs removing
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 fixed quote.
What to include in your enquiry
A good diagnosis starts with the right details. Let us know:
- Clear photographs of the problem areas
- Drawings or a marked-up plan, if available
- The postcode of the building
- Any dates the work must fit around
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or email a schedule or drawings with what you know.
What the job involves on each surface
Window and door perimeters
Internal perimeters are typically sealed with a paintable product where decorating follows. The specification decides which.
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. Snagging can be included or priced separately.
Why deal with it now?
Getting the mastic contractor involved early pays off. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification, which avoids last-minute problems. Called in at the end, the same issues surface during handover. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

- Our applicators hold CSCS cards
- Fully insured
