Frequently Asked Questions

Does the River Slea cause flooding in Sleaford?

The River Slea and its associated navigation channel run through the town centre and have caused flooding in properties along their banks, particularly during prolonged wet spells. Surface water flooding also affects some areas where older drainage systems cannot cope with heavy rain.

My Sleaford property has never flooded. Should I still consider flood defences?

Flood risk is increasing due to changing weather patterns, and many properties that were previously safe are now being reclassified into higher risk zones. Fitting flood defences before you need them also protects your property's value and can reduce your insurance premiums.

What are the most common entry points for floodwater in Sleaford homes?

Doors are the obvious weak point, but air bricks and weep holes account for a surprising amount of water ingress. Many Sleaford properties from the 1960s to 1990s have standard open air bricks that let water flow freely into the subfloor void and ground-floor rooms.

How long do flood defence products last?

Our flood barriers, anti-flood air bricks, and weep vents are built from marine-grade materials designed to last 25 years or more. The rubber seals on barriers should be checked every few years and are inexpensive to replace if needed.

Can GDCG survey my Sleaford property to assess what I need?

Yes. We offer free flood risk surveys for Sleaford properties where we check every potential water entry point and recommend the right combination of products. Sleaford is only about 15 miles from our Grantham base, so we can usually arrange a visit at short notice.
