Drainage problems don't usually announce themselves.

Seasonal pests creep in slowly... one season at a time. Until you wake up one day to find damp walls, soggy lawns or worse... cracks running across your foundation. The thing is... season weather plays a MUCH bigger role in your pest problems than most homeowners realise. Whether it's freezing cold or blisteringly hot outside, each season creates it's own unique type of stress for the ground underneath your home.

The good news?

Knowing a little bit can go a long way. If you know how the seasons affect your soil and drain discreetly, you can prevent issues before they happen.

Why Soil Testing Matters Before Anything Else

Soil testing is the foundation of every good drainage plan.

Guessing at what your soil is composed of is just that, a guess. Clay soils behave drastically differently from sandy soils when it comes to moisture and the elements. Clay absorbs water and expands, sand allows water to pass through rapidly, and loam falls somewhere in between. If you don't soil test, you will never know the exact reason why your yard floods every winter and cracks every summer.

That's especially true in the UK right now. Recent stats revealed that 4.6 million properties face risk from surface water flooding alone - that's 43% higher than past predictions. A lot of it boils down to inefficient drainage on clay-rich soil.

That's a huge number.

If you already have pooling water or unusual cracks in your driveway, you may already need drain services to complete an adequate site survey. A simple survey along with soil testing can prevent you from spending thousands in the future.

Here's the thing about soil testing... It tells you:

• How well your soil absorbs water
• Whether your ground is prone to shrinking and swelling
• If you have hidden compaction issues
• What kind of drainage system will actually work

If you don't have this info, any drain solution you install is a guess.

How Each Season Affects Drainage Around Your Home

Every season brings its own drainage challenges. Here's how each one plays out.

Winter: The Freeze and Thaw Cycle

Winter wreaks havoc on drain fields. Low temperatures allow the water in drains to freeze. Ice expands, breaking apart pipes from the inside. Old clay pipes are particularly susceptible.

When the thaw comes, all of that busted pipework will begin to leak water into the surrounding earth. This softens up the ground around your foundation, leading to ideal subsidence conditions.

It gets worse...

Heavy winter rains saturate the soil. With no place left for water to go, it accumulates around your house, floods basements and finds its weakest point...typically right into your walls.

Spring: The Big Reveal

Spring is the time when winter damage becomes visible. Winter cracks and deficiencies become evident when the soil warms up.

You might notice:

• Sinking patios or paths
• Water pooling in new spots
• Slow-draining gutters and downpipes
• Damp patches on internal walls

Spring is really the ideal time to evaluate drainage because you can still see the problems.

Summer: The Drying Out

Dry summers may be more damaging than wet winters when it comes to clay-rich soil. Clay expands and contracts away from your foundation as it dries.

This creates voids underneath your home that allow it to settle unevenly.

Actually, it's worth noting that the £3 billion shrink-swell hazard across Britain over the last 10 years is primarily summer-induced. Vegetation, including trees and bushes, suck large quantities of water from the soil too.

Autumn: The Leaf Problem

Fall is the forgotten season. Leaves collect in gutter troughs and on top of surface drains, backing up water.

A clogged downpipe will spew hundreds of liters of water directly onto your foundation with one heavy rainstorm.

That's a problem.

The Hidden Damage Weather Can Cause

Seasonal drainage damage does not always become apparent immediately. It can take years for the damage to appear.

Here's what you should be watching for:

• Cracks in walls that get bigger over time
• Doors and windows that stop closing properly
• Damp patches that don't dry out
• Soggy lawns even when it hasn't rained recently
• Cracks in driveways or patios that keep spreading

All of these are indications that water/weather is causing damage beneath the surface. The longer left alone, the more costly it will be to repair.

And the cost is climbing.

Approximately 5.7 million homes are at risk of flooding in England. With 2024 being one of the wettest years on record, drainage failures are on the rise - and costing households more to fix.

Simple Ways To Protect Your Property

You don't have to invest thousands of dollars to keep runoff from damaging your property. These basics work:

Get a Proper Soil Test Done

Rule number one. Before you do anything else, know what type of soil you have. Many drainage contractors will offer a soil test with a complete site survey for a fair price.

Clean Your Gutters and Drains

It seems like a no-brainer, but most people don't think of it often enough. Make sure to clean your gutters and downpipes at least twice a year - springtime and late Autumn.

Install a Proper Drainage System

If your soil test indicates that your yard drains poorly, don't try superficial fixes. Install an adequate system that channels water away from your foundation.

This might include:

• French drains around the perimeter
• Soakaways in low-lying areas
• Regrading ground away from your home
• Installing a sump pump in problem zones
• 
  

Monitor Trees and Vegetation

Large trees remove tremendous amounts of water from the ground during summer. If large trees are within 10 meters of your home, seek professional advice about their potential subsidence risk.

The Takeaway:

The seasonal cycle can greatly impact your drainage needs. Conditions you don't think about the majority of the time can create different issues each season. If left unnoticed, these seasonal changes are one of the quickest ways to develop major structural problems.

The first thing you want to do is start with proper soil testing. Then you can create a drainage plan that will work with whatever Mother Nature gives it.

A little planning today saves you a fortune tomorrow.
