Mastic sealing in Gunville
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. We work on external wall and movement joints, shopfronts below residential blocks and communal entrances and stairwells, and the failures we’re asked to look at most are no planned programme for sealant and a mix of products and colours from past repairs. Searching for sealant specialists in Gunville? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
For owners with a single building near Gunville, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Looking after the joints
Regular inspection catches problems early. Specifically:
- Plan resealing building by building rather than complaint by complaint
- Mention RAMS, insurance or CSCS requirements up front
- Make mastic part of routine maintenance checks
- Reduce knocks to communal area joints
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
What the job involves on each surface
Commercial and mixed-use buildings
Commercial occupiers usually stay open during the work, so we plan around them.
Communal areas
Low-level communal joints get damaged more than most and tend to fail first.

Planned mastic for Gunville portfolios
Gunville has four care or nursing homes no more than 2 miles away. Owners of care premises can bring window and door mastic into a phased programme planned around the home. Gunville sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
Churches, halls and community buildings such as St. Mary's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. If you own or manage units on a site such as Carisbrooke Retail Park, less than half a mile south-east of Gunville, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
Gunville is about 1 mile west of Newport, in the Isle of Wight. Anywhere in PO30, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 125 places in the Isle of Wight, large and small. Portsmouth is covered too, around 13 miles from Gunville.
Business premises anywhere in PO30 are within our area. We cover commercial and managed buildings on Ash Lane, Purdy Road and Gunville Road. We also cover Carisbrooke (1 mile south), Clatterford (1 mile south), Plaish (1 mile south), Bowcombe (1 mile south-west) and Gatcombe (2 miles south). A short drive away, we cover Ryde (7 miles east), Cowes (4 miles north), Sandown (8 miles south-east), Shanklin (8 miles south-east), Ventnor (9 miles south-east) and East Cowes (4 miles north-east). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you speak to us on 01277 525 020 or send photos by email.
Local landmarks in Gunville
We work on buildings around Seaclose Park, Carisbrooke Church of England Controlled Primary School and The Waverley pub and the streets around them. Well-known places in the area include St Mary's Hospital (1.2 miles north-east) and Carisbrooke Castle (0.8 miles south-east). The countryside around Gunville includes Briddlesford Nature Reserve and Mill Hill.
Our process
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Rural sites near Gunville may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
Preparing the site
- Tell staff and tenants when we’ll be in
- Clear stock, furniture or equipment away from the joints
- Send your site hours and access windows
Quotes
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Quoting for work in Gunville
Each job is priced on its own details. The things that drive the figure:
- Removal of failed or old sealant
- Which sealant the job calls for
- Working within restricted access windows
- Backing rod, priming and other preparation
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Sending details for a quote
The more we know, the firmer the quote. When you get in touch, include:
- Rough lengths or quantities, or drawings if you have them
- The postcode of the building
- The product your specification calls for
- Asbestos survey details if the building is older
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, speak to us on 01277 525 020 or use the quote form.
Questions we’re asked in Gunville
Can you work at a site such as Carisbrooke Retail Park, by Gunville?
Yes. We cover Gunville and the area around it, including industrial estates, business parks and retail parks such as Carisbrooke Retail Park. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Is Gunville off your patch?
No. Places such as Gunville are covered as much as the big towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
How long does a job like this take?
It depends on the scope, though a typical visit usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Will residents or tenants be disturbed?
Residents and tenants carry on as normal. If any flats or units need access, we will tell you in advance so you can arrange it with occupiers.
Do you need mastic sealing in Gunville?
Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified it comes away from one face.
Site and facilities staff are often the first to spot these:
- Open joints in brickwork or panels
- A mix of products and colours from past repairs
- Brittle perimeter mastic across a building
- Complaints coming in block by block
With historic buildings such as Carisbrooke Castle, 0.8 miles to the south-east of Gunville, in the wider area, owners of older properties around Gunville should expect mastic to need a product that suits old masonry.
