How we handle construction mastic in Lee
Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list, and every return visit costs time. We seal so the snag list stays short. Site teams most often ask us about early adhesion failures on new external joints and snag items on joints that need redoing before handover, across sanitary and kitchen joints, window and door perimeters and floor and skirting junctions. Most enquiries from Lee start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Lee, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

New build and refits around Lee
Lee sits close to the coast, within about 3 miles. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. There are several hotels within about 2 miles of Lee. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Further education sites such as Totton College, 2.7 miles to the south of Lee, are extended and refurbished from time to time, with mastic often programmed into the summer break. Recladding or extending a unit at a site like Crescent Industrial Estate, 1 mile south of Lee, brings panel joints and frame perimeters into the programme.
Lee is about 2 miles south of Romsey, in Hampshire. Looking for construction mastic in Lee? We can help, as we do across Hampshire. Lee is one of 723 places we cover in Hampshire.

When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Faulty frames rather than failed sealant
- Designing joint widths or choosing the specification (that sits with the designer)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
If in doubt, phone 01277 525 020 or send photos by email and we will say what we think.
Surfaces we seal
- Brick and block movement joints
- Sanitary and kitchen joints

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 the next one starts. For work around Lee, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Before we start on site
- Arrange parking or a loading space
- Share your working hours and any access restrictions
- Share the asbestos register for older buildings
Getting a fixed quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Distance, for remote addresses
- Induction, permit and paperwork requirements
- Working within restricted access windows
- Removal of failed or old sealant
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
Sending details for a quote
To price the job accurately, we need a clear picture of the site. Send us:
- Access details, including height
- The asbestos register, for older buildings
- The type of building and who uses it
- When you need the work done
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or send details through our quote form.

Your questions answered
Is Lee too small for you to travel to?
Not at all. Lee is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you work on a hospital site such as Romsey Hospital?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Can you fit around our programme?
We follow the trades through the building. Areas are sealed as they’re released by the site team.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
How many days will you need on site?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you need construction mastic in Lee?
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with, so gaps outside that range need sorting by the installer first. We flag them early rather than filling them with sealant that won’t last.
Typical triggers for a call:
- Mastic snags holding up handover
- Caulk cracking where joints are moving more than expected
- Sanitary sealant damaged by following trades
- Window and door perimeters that won’t pass inspection
For contractors at a school such as Oasis Academy Lord's Hill, sealing has to be finished before term starts.
