Your satisfaction is our highest priority. If you are not fully satisfied with your treatment results, Shawsheen Valley Mosquito and Tick Control will re-treat the area at no extra cost. Customers who are not satisfied with the results of their treatment, should contact SVMT within 7 days of treatment so that we may come out and re-treat your property. If, after the re-treatment, you are still not satisfied with the results, SVMT will gladly refund that treatment and any future prepaid treatments.
