Specialist work, handled properly
Some jobs need specific expertise. Our specialist team handles Japanese knotweed treatment and eradication, flood prevention measures, retaining structures and other complex site works that sit alongside our main construction services.
What we do
Japanese knotweed eradication and flood prevention works, handled by experienced specialists. Every project is managed by our own team from the first conversation to the final sign-off.
Site problems we solve across West Wales
Some sites arrive with problems that sit outside normal building work. Japanese knotweed is established along riverbanks, railway corridors and old spoil ground throughout Ceredigion, Carmarthenshire and Pembrokeshire, and it can halt a sale or a planning application until it is properly treated. Our specialists survey, treat and monitor knotweed with documented programmes that give lenders and buyers the paperwork they ask for.
Flooding is the other recurring one. Properties in the Teifi valley and around Cardigan have seen repeated flood events, and prevention work — drainage improvements, barriers, raised thresholds and carefully shaped landscaping — can make the difference between a site that insures and one that does not. Both problems are manageable once they are properly diagnosed; the expensive version is the one that gets guessed at.
What it costs & how long it takes
Specialist work is priced after a survey, because the difference between a straightforward job and a complex one is invisible from the road.
Herbicide knotweed treatment typically runs over two to three growing seasons with monitoring; excavation resolves a site in weeks. Flood prevention work is usually scheduled in weeks, timed to avoid the winter flood season. Where a sale or purchase depends on the work, we schedule to the conveyancing timeline and provide the reports solicitors ask for.
