How long will it take to replace my Poly-B? 

Usually Poly-B can be replaced in 2-5 days depending on the size and complexity of the work involved. 

The amount and size of wall and ceiling openings depend on the location and layout of the Poly-B within your home. Reputable plumbers will minimize the amount of drywall opened, opting for strategic access points. 

Experienced drywallers (which Great White Mechanical can subcontract out for you) patches up these openings with utmost precision and care, resulting in finished jobs that look good as new!
