About SmartDry Ltd

SmartDry Ltd is an innovative company with a strong history of expertise in the damp proofing industry.

The company was founded in Holland and is now owned by Iwan Schrijver, the director of SmartDry Ltd in the UK. Henk Schrijver, his father, invented the patented and award winning System for eliminating damp issues.

Compared to traditional methods of damp proofing that use chemicals or replastering techniques that can be ineffective and quite messy, the SmartDry is a green, hassle-free and permanent damp solution.

How it works :
The SmartDry DryBricks work differently from traditional methods by using the natural airflow around a property to actively remove moisture from damp walls.
Once the walls have dried, the the DryBricks continue to work by ensuring a positive ventilation balance throughout the life of the property. SmartDry offers a unique and permanent damp solution.

Installation :
A typical installation will only take one day.
The DryBrick are installed on the outside of exterior walls, so there is no need to work inside the property. This makes the installation process quick and won't disrupt the current resident of the property, which is ideal for both homeowners and landlords.

To ensure high customer satisfaction levels, SmartDry Ltd never outsources any work to 3rd party contractors. Each installation is done professionally by our in-house trained engineers who exclusively use and understand our products.

If you are experiencing damp problems make sure to have one of our damp proofing engineers come and evaluate if Smartdry is right for you.

  • Large damp walls in the living room

    Terrible workmanship, awful customer service - avoid at all costs.

    On 6th August 2019, I paid for the SmaryDry to provide a damp proofing solution for my property.

    On 3rd November 2019, I contacted SmartDry to notify them that the dampness within the wall remained, and appears to have worsened. I asked for a consultant to visit the property but was told this was not possible.

    On 1st July 2021, I contacted SmartDry by phone to notify them that the dampness within the wall remained. At the time, I was selling the property and the buyers arranged for a surveyor to visit the property. Within the surveyors report, the surveyor noted dampness within the wall. SmaryDry spoke with the prospective buyers of the property and confirmed that the SmartDry guarantee is valid. The buyers subsequently pulled out of the property as they had concerns that the damp issue would not be resolved by SmartDry within the required timeframe.

    In May 2022, I tried to remortgage the property. The surveyor from the mortgage company refused to remortgage the property due to very high levels of damp. A damp reading was completed on the walls that SmartDry had treated. This showed a 'very high' and 'wet' reading of 59.8. As such, I am unable to remortgage the property and am suffering financial consequences.

    The customer service is non-existent (I have tried to contact them multiple times in May 2022 without any response). Avoid at all costs.

    Professional, competent. No hard sell. Surprisingly, despite using an alternative approach to damp proofing in the UK, the cheapest estimate.
    I would highly recommend SmartDry. The system does not use chemicals, it achieves life time results by ventilating the walls by using a system of hollow bricks. The workmanship was excellent and the engineer was conscious of keeping down the dust.
