Planned mastic for Lee-on-the-Solent portfolios
With the shore within about 1 mile, Lee-on-the-Solent counts as a coastal location. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Rainfall across the South East, Lee-on-the-Solent included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.
Property owners at sites such as Brockhurst Gate Retail Park (to the north-east of Lee-on-the-Solent) can have mastic renewed between lettings. Trustees of buildings like Church of St Faith can bring frame and external mastic into a planned maintenance list. For a school such as Lee-On-the-Solent Infant and Nursery School, perimeter mastic on windows and doors is a holiday job.

Mastic sealing in Lee-on-the-Solent, done properly
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. If you are dealing with patchy repairs in mismatched sealant and window mastic that has split and shrunk, we can put it right. Facilities teams, main contractors and managing agents in Lee-on-the-Solent tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For landlords and associations with stock in and around Lee-on-the-Solent, grouping buildings into one visit saves travel. Send the addresses and photos and we will quote for all of them together.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Why act early in Lee-on-the-Solent
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. In a smaller place such as Lee-on-the-Solent, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Questions about Lee-on-the-Solent
Can you quote for a block close to Fareham station?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Does your area include sites such as Brockhurst Gate Retail Park, near Lee-on-the-Solent?
Yes. Our area takes in Lee-on-the-Solent and its surroundings, with estates and business parks such as Brockhurst Gate Retail Park included. A few photos and the unit address let us price the work.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so it can be arranged.
Do you supply RAMS and insurance details?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
What the job involves on each surface
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
Commercial and mixed-use buildings
Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. We work across portfolios on a planned basis.
How a job runs
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. For a site in Lee-on-the-Solent, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

Other services in Lee-on-the-Solent
Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
What affects the price in Lee-on-the-Solent
What shapes the price:
- Any access equipment needed
- The site’s rules and procedures
- The product specified
- Whether old sealant has to be cut out first
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.
What we need to price the job
We can often quote from photographs and a few details. Please tell us:
- When you need the work done
- The site address and postcode
- Asbestos survey details if the building is older
- Photos of the joints, close up and from further back
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
