Arlington, MA Basement Waterproofing, Explained
Arlington, MA is a town, not a city, with 46,308 residents in the 2020 census. It sits about 6 miles northwest of downtown Boston in Middlesex County, and the Minuteman Bikeway runs across it. Its basements face melting snow, nor'easters and sudden summer downpours.
Think of this site as a switchboard rather than a builder. It holds no Massachusetts Home Improvement Contractor registration, gives no prices and signs no contracts. It puts you in touch with one independent contractor, and everything after that, from the visit to the paperwork, stays between the two of you.
What Arlington, MA Basement Walls Are Made Of
The wall material shapes the repair. Greater Boston has many older fieldstone and brick foundations, held together by mortar that can soften with age and let water in more readily. Concrete block is hollow inside and can hold water before any dampness shows on the surface. Poured concrete usually stays tight except at cracks and at the cove joint, where the wall meets the floor.
Can't tell what sits behind the paint in your Arlington basement? A visiting contractor can tell you, and the wet basement checker asks about wall type too.
Services in Arlington, MA
Start with what you're actually seeing.
- Seepage along the floor. Water at the base of a wall often calls for an interior drain and sump; full basement waterproofing covers how those systems work.
- A leak after storms. If one spot gets wet only in heavy rain, begin with basement leak repair, which walks through tracing the source.
- Cracked or crumbling walls. Injection suits many poured-wall cracks, and repointing suits stone and brick. A horizontal crack or a bowing wall is worth having looked at soon. See foundation crack repair.
- An old or missing pump. Ask about battery backup and a high-water alarm. Read up on sump pump installation.
- Water from the yard. Downspouts that empty beside the house and soil sloping toward it are common culprits; basement drainage explains the fixes.
Wet Weather and Arlington, MA Basements
There's no Arlington rain gauge in these records. The numbers come from Logan Airport, per the National Weather Service as reported locally, and show what the wider region can get.
- Spring 2010. A March storm brought 6.8 inches to Logan, and many basements around Boston flooded.
- Summer 2021. By mid-July, Logan had logged nearly 9 inches, and the month ranked as the third-wettest July on record.
- Late 2023. December delivered almost 6 inches at Logan, well above its usual total of just over 4 (Boston Globe).
Water that comes up through a floor drain, though, usually means the sewer is backing up, not that the walls are leaking. The Boston Water and Sewer Commission serves Boston only, so Arlington residents should ask the town about sewer backups and backwater valves before anyone sells them a drainage system.
Permits From Arlington, MA Inspectional Services
Arlington, MA runs its own Inspectional Services office at 51 Grove Street, reachable at (781) 316-3390, Monday through Friday from 8 to 4. Permits move through the town's online permitting portal. The town doesn't post a rule on whether a sump or an interior drain by itself requires a building permit, so call the office and ask before work begins.
Any plumbing involved carries a separate permit. Your contract should name which permits the contractor will pull and where the sump line will drain; check with the town before that line ties into anything.
Planning a Budget in Arlington, MA
There's no published price data for Arlington alone, so the table pairs Angi's Boston-area range with Fixr's national rates.
| Cost row | Figure | Source (year) |
|---|---|---|
| Typical basement waterproofing project, Boston | about $2,109 to $6,243 (average about $4,116) | Angi, Boston (2026) |
| Interior perimeter drain, per linear foot | $40 to $120 | Fixr national (2026) |
| Sump pump installation | $600 to $2,500 | Fixr national (2026) |
| Epoxy crack injection, per crack | $250 to $1,000 | Fixr national (2026) |
| Waterproof paint or sealant, per sq ft | $1 to $8 | Fixr national (2026) |
Your total depends mostly on the length of drain, whether a pump is part of the job and how many cracks get sealed. Paint and sealant cost the least, but on their own they rarely hold back water under pressure. Run the cost calculator for a ballpark, then hold it up against the written estimate.

Common Questions in Arlington, MA
Where do I ask about permits in Arlington, MA?
Call Inspectional Services at (781) 316-3390 or stop by 51 Grove Street on a weekday between 8 and 4. Applications go through the town's online portal. With no published rule for drains or sump pumps alone, ask the office what your job needs.
Does the Boston Water and Sewer Commission cover Arlington?
No. BWSC serves the City of Boston, and Arlington is its own town. For questions about sewer backups, backwater valves or where a sump line is allowed to drain, contact the Town of Arlington. If dirty water ever comes up through a floor drain, treat it as a possible sewer problem rather than a leak in the walls.
Does this site send someone to inspect my basement?
No. This site never inspects, assesses or works on basements. It forwards your request to one independent contractor, who arranges any visit and prepares the estimate under their own name.
How do I check a contractor's Massachusetts registration?
Ask for the contractor's Home Improvement Contractor registration number and look it up with the state's HIC program. Structural work also calls for a Construction Supervisor License. The registration number belongs on the written contract, along with the drain length, pump model and discharge route. Ask the contractor and the HIC program about deposits and your right to cancel.
Is a damp basement covered by my homeowners policy?
Plenty of policies leave out slow seepage and groundwater, and sewage backup coverage is often sold as an extra. Read your own policy and talk with your agent before you count on anything. This site doesn't file or manage insurance claims.
