Water damage and mould remediation in Boston

Restoration firms for drying and mould removal.

55 pros in Boston

Water damage in Boston often starts at the harbour or in the sewer line. During the January 2018 nor'easter, USGS recorded a stillwater elevation of 9.66 feet in the city, a level with an annual exceedance probability of between 2 and 1 percent. Boston Water and Sewer Commission also points to backwater valves on fixtures below street grade and a floating floor-drain plug at the lowest part of the basement, which tells you where backups tend to enter a home. When you hire for drying out or mould removal, ask what the crew will do first to bring the space back to a dry state, since the Commission calls that one of the most important steps after a sewer backup. Ask for a written scope that covers drying, removal of damaged materials and any mould work. Also ask how the work will be documented, because your insurer may ask. Check that the business can show the licences and insurance it holds before you sign anything.

Questions about hiring in Boston

What should a water damage or mould quote include?

Ask for a written scope that lists the rooms affected, how the space will be dried, which materials will be removed, and what mould work is planned. It should state who does each step, the expected timeline, and how the work will be documented. Compare quotes on scope, not just the total, so you are weighing the same job.

Does my homeowner's policy cover flood damage in Massachusetts?

According to the Massachusetts Division of Insurance, a standard homeowner's insurance policy does not cover flood damage, and no state law requires you to buy flood insurance. Check your policy and any separate flood coverage before you commit to a restoration contract, so you know what may be reimbursed.

Who do I call first if a pipe bursts?

For water damage not caused by flooding, such as a burst pipe, the Massachusetts Division of Insurance tells homeowners to contact their home insurance company. Contacting your insurer early lets you learn what documentation it wants before cleanup begins, and then you can brief any restoration business accordingly.

What matters most after a sewer backup in Boston?

Boston Water and Sewer Commission says that once a backup or overflow is resolved, the most important cleanup steps are restoring the environment to a dry state and salvaging valuable property. When you talk to restoration businesses, ask how they will dry the space and how they will handle items you want to keep. Boston Water and Sewer Commission (source, opens in a new tab)
