Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Sites and facades in and around Liss
A number of hotels sit less than 2 miles from Liss. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. Liss is about 47 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
School extensions, at buildings such as Liss Infant School, typically run to the summer holidays, mastic included. For a contractor working at a hospital such as Petersfield Community Hospital, 3.6 miles south-west of Liss, perimeter and facade sealing is planned around patients and deliveries.
Liss is about 3 miles north-east of Petersfield, in Hampshire. Any commercial site in Liss is covered, whether it’s a single job or part of a planned programme. Liss is one of 723 places we cover in Hampshire for mastic packages. Sites around Portsmouth have their own page, roughly 18 miles from Liss.
Business premises anywhere in GU33 are within our area for mastic packages. Buildings on Station Road, Shotterfield Terrace and Greenfields are within our area.

Construction mastic in Liss
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 the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. We work on cladding and panel joints, sanitary and kitchen joints and brick and block movement joints, and the usual reasons a site gets in touch are sealant knocked or painted over by other trades and a long mastic snag list close to completion. Facilities teams, main contractors and managing agents in Liss tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In a smaller place such as Liss, construction tends to mean small housing schemes, conversions and extensions to community buildings. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
Our workmanship is guaranteed for 12 months, in Liss as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What happens if it’s left?
Sealing over damaged or contaminated new joints might save a day, but it won’t last. New sealant laid on old or dirty sealant has nothing to bond to. We cut out and redo the joint properly. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
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.

Signs you need construction mastic in Liss
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.
Things that typically lead to an enquiry:
- Frame perimeters left unsealed or poorly sealed
- Existing joints on a refurb that need cutting out and resealing
- Oversized or tapered gaps around new frames
- Inconsistent sealant finishes from plot to plot
New units and refits on sites such as Ham Barn Business Park, 1.3 miles to the north-west of Liss, need their panel and perimeter joints sealed to the specification.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- Their pre-qualification and accreditations
- Their approach to joint depth and backing
- The named product and why it was chosen
Cost factors for mastic packages
Before we quote, we look at:
- Whether old sealant has to be cut out first
- Access and working height
- Specialist products, such as fire-rated or hygienic sealants
- Whether the work must be split into stages
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you’re ready.
Details that help us quote
A few photos plus some basic facts will normally do. It helps to include:
- The product your specification calls for
- Drawings or a marked-up plan, if available
- Whether the building will be occupied during the work
- The site address and postcode
For a fixed quote, call the office on 01277 525 020 or email the details over with the site address and an outline of the work. Our quote form is another easy route.
After the work
Regular inspection catches problems early. In particular:
- Ask for joint and product checks before the package is urgent
- Put any product change through the designer first
- Don’t schedule sealing before decorators and flooring are done
- Protect sealed areas from following trades
Record which products went where in the handover file. That helps the building owner maintain the joints later and avoids guesswork when joints are renewed. We can confirm the handover information you need when we quote.
External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.
Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Several jobs near Liss can be grouped on one trip. Mention the building’s opening times and we will work within them.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- 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.
Before we start on site
- Confirm the product named in the specification
- Share your working hours and any access restrictions
- Point out parking and an unloading spot
