Vermont basement estimate comparison
Compare basement waterproofing estimates: the work, not the totals
Two proposals for the same wet basement can differ by thousands of dollars and still describe different jobs. Line up the scope first, then compare price.
Choose by comparing measured work, water collection and discharge, equipment, structural responsibility, demolition, restoration, maintenance, warranty and total installed price. A recognizable product name or low headline price does not show whether two proposals cover the same job.
A fair second estimate
It is a check, not a contest
Ask the second company to price the problem the first one saw, or to say why it sees a different one. If the diagnoses match and the prices differ, compare the eight lines below, because the gap is almost always in quantities, restoration, discharge or warranty terms that one bid spells out and the other quietly leaves for later, after the contract is signed. If the diagnoses differ, that is the finding.
Neither number means much until you know which cause is real. A basement that leaks at the wall-floor joint is not fixed by crack injection. A bowed wall is not fixed by a sump. Ask each company to point at what it saw.
Photos help. So does a note of the date and the weather when the water appeared. Bring both to every visit.
Line by line
Eight lines that have to match
| Line | What to compare | Why it matters |
|---|---|---|
| Measured work | Linear feet of drain, number of piers or anchors, square feet of liner, each with a location | A total with no quantities cannot be checked against a second bid |
| Water collection and discharge | Where collected water goes, the outlet, and what happens when the power fails | A system that collects water and has nowhere safe to put it fails in the first storm |
| Equipment | Pump size, backup power and alarm, dehumidifier capacity, with the installed model named | Two pumps with the same price can differ several-fold in flow at the actual discharge height |
| Structural responsibility | Who specifies wall or floor reinforcement, and whether an engineer is involved | Water work and structural work are different scopes with different accountability |
| Demolition and access | What is opened, what is finished space, and who repairs it | Finished basements turn a modest quote into a large one when this line is silent |
| Restoration | Wall, floor, trim, landscaping and grade after the work | Restoration is the most common line missing from the cheaper bid |
| Maintenance | Filters, pump testing, dehumidifier service, and who does them | A dry basement depends on equipment that must keep running |
| Warranty | Term, what is covered, whether it transfers, and who honors it | A warranty is only as good as the entity that stands behind it |

Estimate FAQs
Direct answers for homeowners comparing proposals
Should I get more than one basement waterproofing estimate?
A second estimate is useful when the project is expensive, the proposals recommend different systems, structural work is involved or the first scope does not clearly explain quantities, discharge, restoration, maintenance and warranty.
Can two waterproofing estimates describe completely different repairs?
Yes. One may emphasize interior drainage and a sump while another recommends exterior excavation, crack work, grading or structural repair. Compare what each component does and which observed condition supports it.
What should the name on a basement contract match?
The business that carries the insurance and gives the warranty. Ask for the exact legal entity in writing and check it against the certificate the insurer sends you directly.
Does this site recommend a waterproofing company?
Champlain Valley Basement & Foundation takes a description of the problem and arranges an inspection. It does not rank or rate other companies, and no company pays for placement here.
Sources and Vermont specifics
What a comparable basement contract has to show
Vermont law sets a floor for the paperwork. Residential contractors doing construction valued at $10,000 or more must be registered, must attest to using a written contract that includes the price, work dates, scope of work and a change order provision, and must carry liability insurance of $1,000,000 per occurrence and $2,000,000 aggregate. Those four contract items are the first four lines of any comparison.
If one estimate spells out all four and the other gives a total and a handshake, the totals are not comparable. Put the two proposals side by side on the eight lines above, then add the registration number and the insurance certificate. A gap in either is worth a question before it is worth a discount.
Keep a simple comparison sheet. List each company across the top and the eight lines down the side, fill in what each proposal states, and mark blanks in a different color. Blanks matter as much as numbers. When one company has filled a line and another has left it blank, ask the second whether the item is included, excluded or forgotten, and get the answer in writing. That single habit resolves most of the confusion between estimates.
