Our services are available 24/7, 365 days a year.White Box was founded to solve a persistent problem. After years of experience as a construction manager in residential developments, I constantly faced the same problem: cleaning and mastic services offered in two separate packages, leaving a gap in coordinated services. ​Frustratingly, this gap reduces efficiency and increases abortive visits, a problem all too common in the building industry. ​WhiteBox solves the problem by managing the entire process, coordinating both mastic and cleaning services and consistently holding quality control meetings.​We offer a fully integrated cleaning and mastic service or subject to your needs offer cleaning and mastic services separately. ​We go above and beyond by working closely with clients providing structured management plans to guarantee full transparency and flawless results.
