What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Leaks from above rather than through a joint
- Masonry that has broken away beside the joint
- Failed window or door frames, which need a window contractor
If you’re not sure, just call the office on 01277 525 020 or use the quote form and we will give you a straight answer.

Mastic sealing in Bitterne Manor
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. We work on communal entrances and stairwells, communal kitchens and washrooms and balcony and threshold joints, and the usual reasons a site gets in touch are window mastic that has split and shrunk and open joints in brickwork or panels. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Bitterne Manor, that means joint design, primers and backing rod as standard.
For landlords and associations with stock in and around Bitterne Manor, grouping buildings into one visit saves travel. Send the addresses and photos and we’ll quote for all of them together.
The 12-month guarantee covers our workmanship: 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.

For owners and agents in Bitterne Manor
The sea is no more than about 2 miles from Bitterne Manor. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, and they deserve more regular inspection. Bitterne Manor is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building typically need attention first.
Landlords with units on estates such as Bitterne Business Centre (less than half a mile east of Bitterne Manor) can bring frame, door and external mastic across several units into one programme. For agents with blocks near Bitterne station, under half a mile to the east of Bitterne Manor, a block-wide mastic programme deals with frames, balconies and entrances in one go.
Bitterne Manor is about 1 mile east of Southampton, in Southampton. Across the SO18 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Southampton, 30 places are covered, Bitterne Manor among them.
Business premises anywhere in SO18, SO17 and SO14 are within our area. For a building on Ivy Road, North Road and South Road or nearby, send details and we will quote for mastic joints. Just outside Bitterne Manor, we also work in St Denys (1 mile north-west), Southampton (1 mile west), Northam (1 mile south), Bitterne Park (1 mile north-east) and Portswood (1 mile north-west). Bigger towns within reach include Regents Park (3 miles west), Maybush (3 miles west), Coxford (3 miles north-west), Lordswood (3 miles north-west), Millbrook (3 miles west) and Redbridge (4 miles west).

Aftercare for building managers
For the best life from the joints:
- Keep a record of when each building was resealed
- Mention RAMS, insurance or CSCS requirements up front
- Start inspections with the most exposed faces
- Make mastic part of routine maintenance checks
If paintable sealant was used, decoration can follow once it has cured. Silicone normally can’t be painted, so keep decorators off it.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.
What we are called out for in Bitterne Manor
UV and rain age external sealant. It stiffens, stops stretching and cracks, especially on south and west faces.
Common reasons buildings call us in:
- Brittle perimeter mastic across a building
- Draught complaints from residents or tenants
- Failed external movement joints
- Leaks at window and door perimeters
If you are responsible for a building such as Church of St Denys, frame and door mastic needs the same attention as any other property.

- Removal of failed or old sealant
- Working within restricted access windows
- Induction, permit and paperwork requirements
- Backing rod, priming and other preparation
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
Details that help us quote
There’s no need for a formal survey. These details are enough to start:
- When you need the work done

- Anything awkward about access or site hours
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or send details through our quote form.

Related advice
Bitterne Manor: questions and answers
Can being near the sea in Bitterne Manor affect the sealant we need?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Is Bitterne Manor too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What will the job cost?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Leave it or put it right?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Pricing mastic joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.
