EWI Repair & Maintenance

As a specialist installer of external wall insulation (EWI) and silicone rendering, we also offer maintenance and repair services to ensure your home stays protected and looking great.

While external wall insulation is generally a low maintenance measure, it’s important to ensure that everything is in order and maintained correctly. This means any warranties you have stay valid, and your home is warm and safer from the elements.

  • Ensures your warranty stays valid

    Ensure your existing warranty stays valid in case of future problems

  • Keeps your home looking great

    Good maintenance keeps your render and your home looking fantastic

  • Gives you peace of mind

    Unexpected problems can be a nasty surprise, we’ll help you find and fix them before they can become a disaster!

  • Identify problems before they become serious

    Our condition report is a full and thorough inspection carried out by one of our expert surveyors.

Our Process & Maintenance Plans

Option 1 - The Condition Report

If you’re concerned about any issues with your property, or you want peace of mind in checking areas that you think could be a problem then this plan is the one for you.

Once you get in touch we’ll take down some details about your property, book in an appointment at a convenient time for you and let you know what the cost of the report will be. One of our experienced team will then visit to conduct the condition report on the EWI or Render of your property.

If you have any warranties, paperwork or other information about the external insulation or render that has been installed at your property then having it available may assist the surveyor and help them answer any extra questions you may have.

Our expert surveyor will then conduct a complete and thorough inspection on the external elevations on your property. They will examine the following key areas:

  • All external elevations of the property to check the condition
  • Areas around pipework
  • Seals
  • Areas around cills & reveals

During the inspection photographs will be taken of your property.

Once the inspection has been completed we’ll inform you of any problems we have found and provide you with the report outlining this. We’ll also help you to understand how we can go about fixing the problem, what might have caused it and how to prevent the issue reoccurring. If problems are found in the report then our remedial plans will help you to resolve the issue quickly and professionally.

Minor Remedial Plan

If there are specific issues that you are aware of that need fixing, or if our condition report has identified minor problems then our minor remedial plan is for you.

Our minor remedial plan covers the following:

  • Repairs such as cracks to areas around cills and reveals
  • Fixing minor damage to specific areas
  • General repairs to small areas of elevations

We work with you to identify the issue, confirm the required fix and get a quote to you to provide a professional fix at our usual high quality.

When your quote has been finalised and written up you’ll receive an email containing the quote in pdf format. If you have any problems viewing or accessing your quote let us know and we’ll be happy to assist!

Major Remedial Plan

Sometimes damage, the elements or other factors may cause your EWI or render to require greater maintenance, that’s where our major remedial plan comes in. Our team will be ready to bring fresh life back to your render and resolve larger scale damage to ensure everything is as it should be.

The major remedial plan covers the following areas:

  • Fungicidal Wash to property elevations
  • Large scale repairs
  • Repainting or retexturing of property elevations
  • Brick slip damage
  • Fill-in works where items on the wall have been removed (i.e Gas Meter boxes)
  • Deep impact damage

If your render is off colour, or has been installed for a long while and needs attention then our expert teams will help explain what can be done for your specific system and how we’ll be able to help. We work with you to identify the issue, confirm the required fix and get a quote to you to provide a professional fix at our usual high quality.

We know that sometimes warranties, maintenance and potential problems can be a headache to deal with and understand. While all of our installations come with clear instructions and easy to understand warranties this unfortunately not always the case with other installers.

That’s why we’re able to provide support to help identify and problems with your insulation or render and can help to put things right in a simple and hassle free process.
