Questions about Fratton
Is The Bridge Shopping Centre, near Fratton, within your area?
Yes. Estates, retail parks and business parks around Fratton, The Bridge Shopping Centre among them, are all within reach. A few photographs and the unit address let us price the work.
Could you schedule work at a campus like University of Portsmouth for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How do you work with the site programme?
The programme sets the job. Share the release dates and we’ll match our work to them so sealing follows the trades.
How do I request a quote?
The quote form is the simplest route, though you can also call 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Can the building stay open while you work?
In most cases, yes. Phased work can be planned so areas stay in use.
Construction mastic for commercial buildings in Fratton
Most of the packages we price run well beyond frames: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. One contractor for all of it keeps the responsibility in one place. If you’re dealing with sealant knocked or painted over by other trades and missed perimeter joints on a new elevation, we can help, whatever the surface. Searching for sealant specialists in Fratton? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Conversions around smaller places like Fratton often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Oversized gaps that need packing or adjustment by others
- Faulty frames rather than failed sealant
- Rework caused by others damaging completed areas
If you’re not sure, just speak to us on 01277 525 020 or email the details over and we’ll give you a straight answer.
What we seal
- Floor and skirting junctions
- Sanitary and kitchen joints
- Cladding and panel joints
- Brick and block movement joints
- Window and door perimeters
- Internal decorators’ caulk
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
What else we do in Fratton
For managing agents and facilities managers
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Signs you need construction mastic in Fratton
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We stick to the specified product, or put any alternative to you first.
What tends to prompt an enquiry:
- Perimeter gaps outside the sealant’s range
- Snag items on joints that need redoing before handover
- Inconsistent sealant finishes from plot to plot
- Window and door perimeters that won’t pass inspection
Hotels like Eastfield Hotel, 0.9 miles south-east of Fratton, rarely close for long, so refurbishment mastic is phased floor by floor.
What your quote should include
- Can the work be phased to keep areas open?
- How long is the guarantee, and what does it include?
- How the existing material will be dealt with
- Whether primer will be used where the manufacturer specifies it
Aftercare for building managers
Once the work is signed off, these steps help:
- Keep product details for future maintenance
- Protect sealed areas from following trades
- Keep scrapers and abrasive pads off new beads
- Get the mastic subcontractor involved early in the programme
Record which products went where in the handover file. Future maintenance is easier when the products are known, and tells you what to reseal with. We can confirm the handover information you need when we quote.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last so packing or adjustment by the installer comes first. We flag them as soon as we see them.
How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Work in places the size of Fratton is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.

- Agree which areas must stay open
- Tell us what induction or permit system the site runs
- Tell us your opening times and when work is allowed
