Why it’s worth doing now in Ower
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Leave it late and they turn up on the snag list. Around Ower, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.
Pricing mastic packages depends on quantities, condition and access, plus any specification you are working to. Call for a quote.
Why appoint us
- Commercial sealant work since 2005
- A Constructionline member, so easy to vet
- Coloured sealants to suit the setting, where available
- Health and safety: CHAS accredited

Construction mastic for commercial buildings in Ower
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. After that, the joints are prepared and sealed to the specification. We work on cladding and panel joints, floor and skirting junctions and sanitary and kitchen joints, and what we’re called in for most is failed sealant in an existing building being refurbished and a mastic package split between trades with no clear owner. Searching for sealant specialists in Ower? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Construction in and around smaller places such as Ower 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.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Questions we are asked in Ower
Could you schedule work at a campus like Totton College for the vacation?

Do you do internal caulk as well as external mastic?

Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Construction mastic around Ower: what changes locally
The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.
Older buildings in the area around Ower, such as Landford Manor, which lies north-west of Ower, need care when sealed: the product has to suit soft or historic materials. When a college such as Totton College, 2.1 miles south-east of Ower, builds or refurbishes, the mastic package normally has to fit around students and staff.
Ower is about 2 miles north-west of Totton, in Hampshire. Across the SO51 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. 723 places across Hampshire fall within our area, including Ower. We also cover Southampton, around 7 miles from Ower.

Common problems we fix in Ower
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with and gaps beyond it need packing or adjusting by the frame installer. We flag them early rather than filling them with sealant that won’t last.
It’s worth sending us details if you spot any of the following:
- Different trades sealing to different standards
- Snag items on joints that need redoing before handover
- Existing joints on a refurb that need cutting out and resealing
- Window and door perimeters that won’t pass inspection
Recladding or extending a unit at a site like Mortimer Trading Estate, less than half a mile to the west of Ower, brings panel joints and frame perimeters into the programme.
Before you book anyone
- What the guarantee covers, and for how long
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Health and safety accreditation such as CHAS
- Whether old or failed sealant will be cut out, not overlaid
Cost factors for mastic packages
The price varies from site to site. Expect it to depend on:
- Site requirements such as inductions and permits
- Location, for remote and island sites
- The product specified
- Phasing around occupants
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- How the joints are reached, and at what height
- Where the site is, with the postcode
- What the building is and how it’s used
- Drawings or a marked-up plan, if available
For a fixed quote, ring 01277 525 020 or send photos by email, telling us the site location and the nature of the job. You can also send details through our quote form.
After the work
After handover, a little attention goes a long way:
- Keep finished joints away from paint, plaster and scrapers
- Get the mastic subcontractor involved early in the programme
- Record the products used in the O&M file
- Put any product change through the designer first
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known, and tells you what to reseal with. Tell us what records you need and we’ll confirm with the quote.
Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short, and avoids a rush.
