Mastic sealing for Drayton sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Mastic sealing in Drayton, done properly
Across Drayton and the rest of Portsmouth, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. If you have mastic failing across several blocks on an estate and patchy repairs in mismatched sealant, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Drayton is the same: the right product in a properly prepared joint.
Converted and older buildings in and around Drayton often put modern windows into old walls. The mastic there needs to suit both surfaces.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Share your contractor requirements early
- Track which buildings were done and when
- Start inspections with the most exposed faces
- Reduce knocks to communal area joints
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.
What sets the cost
Each job is priced on its own details. The things that drive the figure:
- Site requirements such as inductions and permits
- How much existing material needs removing
- Whether the work must be split into stages
- The product specified
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Drawings or a marked-up plan, if available
- The asbestos register, for older buildings
- Any dates the work must fit around
- Where the site is, with the postcode
To get a fixed quote, phone 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. Our quote form is another easy route.
Planned mastic for Drayton portfolios
With the shore within about 1 mile, Drayton counts as a coastal location. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, and they deserve more regular inspection. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.
Student blocks close to universities like University of Portsmouth - Langstone Campus, 3.3 miles south of Drayton, are easiest to work on between tenancies. For owners of several units at places like Railway Triangle Industrial Estate, 0.6 miles south-west of Drayton, one programme can deal with frame and external mastic across the lot. Buildings close to stations like Cosham station (to the west of Drayton) are often flats over shops, with frame mastic to keep sound.
Drayton is about 2 miles south of Purbrook, in Portsmouth. Drayton sits inside our coverage and the rest of Portsmouth, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Drayton is one of 19 places in Portsmouth on our list.

Advice
Commercial clients in Drayton
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Building owners and managing agents use us on everything from one building to a spread of sites around Drayton. One quote can cover more than one site, so there’s one set of paperwork to deal with.
FAQs: Drayton
Do you work for managing agents with blocks near Cosham station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Does a coastal location like Drayton affect which sealant is used?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can you seal joints high up on a block?
Every block is different. We agree access with you at quote stage so there are no surprises.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Substrate edges that need repairing first
- Leaks through the frame itself rather than the perimeter
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think.
What we seal
- Window and door perimeters on blocks
