I contacted Septic Tank Repairs when my lines leading to my septic tank had backed up. I had noticed this was happening quite often and i was fed up paying for the lines to be cleared. They came out and told me the baffles were broken in the tank and i could claim for a new tank through my house insurance. They took care of the whole claim and even sorted out a legal issue for me. I now have a new Sewage Treatment Plant with a new Consent to Discharge and I didnt have to pay a penny. My insurance premium has remained the same too. I cannot recommend this company high enough.

From my first contact with Stephen, throughout the entire process to completion and aftercare, STRni have been extremely professional, considerate and helpful. Nothing was too much for the team and no question went unanswered. I cannot rate STRni highly enough!

Septic Tank Repairs NI was a Godsend for me as they took care of everything. Even though my insurance company initially declined the claim they worked tirelessly to get this sorted. The service received was second to none – they are a professional, friendly, sympathetic, helpful and extremely knowledgeable company. I cannot recommend them highly enough.

Stephen and his team carried out a professional job from start to finish. They successfully dealt with my insurance claim , applied for all approvals and installed the replacement sewage system. These guys have the knowledge and expertise that are required to deal with this type of insurance claim, I am very satisfied with the work that was carried out and the end result. Thank you STRni.

Excellent service that took all the stress out of what would otherwise have been a very disruptive experience, after our existing tank failed. Insurance settlement was secured in full. The work was commissioned, managed and carried out courteously and with genuine concern for a stress-free process and good final result. After installation we were given expert advice and a swift response in person to our questions. Highly recommended.

Highly recommended. The complete job from beginning to end was excellent. The communication was great and I was kept informed at all stages of the work. The whole team were courteous, efficient and a pleasure to have at our home. Delighted to have my new system fitted. Thanks again.

If it wasn’t for Septic Tank Repairs NI I would have been out of pocket to a great expense. I thought I had no chance pursuing a claim on my own and with work commitments; I simply didn’t have the time, the expertise or the dogged determination to deal with my insurance company and their agents. STRni took care of everything for me. The investigations, dealing with my Insurers, liaising with my neighbours and land owners, design, construction, building control application, everything from start to finish. My garden looks like new and I now have a fully functioning Sewage Treatment Plant which will last for years. All at absolutely no expense to me.  A wonderful team of professionals throughout

I first contacted Septic Tank Repairs NI in July 2020 having been unable to resolve my claim directly with my Insurance Company.  I immediately felt reassured by the very apparent expertise and experience of their team.  They advised on the process and their Claim Consultant INSCO was outstanding. This team overcame whatever hurdles arose and inspired confidence in their technical capability and managerial aptitude. The works were completed at my property in November 2020 and I truly believe they have carried out a really good job that will function well for years to come. Consequently, I have nothing but praise and gratitude for this company.

We first became aware that my septic tank had collapsed following our annual cleaning. My husband and I had no idea what to do so we contacted our local tank suppliers. They recommended Septic Tank Repairs NI to process our Insurance Claim and install a new tank. Stephen and his team were a Godsend.

His men were exceptionally tidy and courteous. All the statutory consents and claim work was done efficiently and professionally by Stephen and Gary. We had no idea how much work was involved and they kept us informed, step by step, at all times. We were delighted with the work and were left with the lawn almost perfect.  The service was very professional and we have no hesitation in recommending this company. Excellent service, with no stress.
