Most property owners spend a considerable amount of money on maintaining the outward appearance of their home, especially when it comes time to sell. The last thing on any homeowner’s mind is the state of their plumbing system.
But did you know that a neglected drainage system can actually have a negative effect on your property’s value?
Research by Aviva found that four out of five UK homebuyers would reduce their offer if they spotted maintenance issues, including blocked drains. The insurer also cited research suggesting that poor property maintenance can reduce a home's value by an average of 14%.
While many individuals associate an increase in property value with a beautiful lawn or a modern kitchen, the connection between a well-maintained plumbing system and higher property value is unmistakable.
First Impressions Matter
They say it only takes someone a tenth of a second to make a first impression, giving rise to the idea that having a beautiful home is essential to getting the right price for your property. However, waterlogged gardens, overflowing drains, bad odours, and growing mould can quickly undermine that first impression. These visible warning signs may cause potential buyers to question how well the property has been maintained and whether more serious drainage or structural issues could exist, making them more hesitant to submit a competitive offer.
Structural Damage Can Be Pricey
Long-term drainage issues can contribute to soil erosion, damaged paving, cracked walls, and much more. This structural damage not only has a negative impact on your property’s foundations, but its market value as well. Addressing blocked drains as soon as they occur are one of the easiest ways to protect your property’s value and prevent any permanent damage that could affect the long-term value of your home.
Prevention is Cheaper Than Repairs
A poor drainage system has the potential to become a costly problem if left unchecked. Small warning signs like a consistently blocked drain or foul smells require immediate attention before they snowball into severe plumbing issues.The truth is, buyers don't want to spend more money dealing with potential drainage issues after purchasing a property. If a home shows visible warning signs of plumbing or drainage problems, many buyers may be discouraged from making an offer or choose to walk away altogether. Regular drain maintenance is one of the most effective ways homeowners can prevent hidden plumbing issues before they become costly repairs, safeguarding the value of your property.
What Homeowners Can Do Before Selling
If you’re planning to put your property on the market, one of the best ways you can preserve your value and plumbing systems is by addressing drainage issues beforehand. While first impressions matter, even relatively small issues such as slow-draining sinks or unpleasant odours can cause potential buyers to run for the hills.
Before listing your home, consider taking the following steps:
Clear leaves, debris, and other blockages from external drains and gutters.
Address slow-draining sinks, showers, or toilets before they become larger issues.
Repair damaged or overflowing drains.
Schedule a professional drain inspection or CCTV drain survey if you've experienced recurring blockages or suspect an underlying problem.
Resolve any damp or mould caused by drainage issues.
Keep records of any drainage maintenance or repairs to reassure prospective buyers.
Taking small steps to address your property's drainage problems is just one way to improve its overall marketability. Investing in preventative maintenance now is often far more cost-effective than facing expensive repairs or accepting a lower offer due to avoidable drainage problems.
