01 Agreement
These terms are between you and National Lumber & Building Materials Co., an independent Rhode Island corporation. Using this site means you accept them. If you are using it for a company, you are confirming you may accept them on that company's behalf.
These terms cover the website. A signed quotation, purchase order or supply agreement covers an actual order, and where the two disagree, the order documents win.
02 What this site is
National Lumber is a turnkey building partner. This platform provides plan intake, preliminary takeoffs, customer accounts and project records. Submit your drawings, review your preliminary takeoff, request team review and follow your approved proposal and order.
Individual materials are not sold through this platform. An automated takeoff or request for review does not place an order, reserve materials or create a payment obligation. Our team must issue a reviewed proposal before you can approve its terms and proceed to payment.
A received reference confirms that the server saved your request. It does not mean a takeoff is finished, a quote has been issued or a purchase has been paid. Use the saved status and conversation in your account to follow the next steps.
03 Takeoffs and quotes
Framing takeoffs and package quotes are free and carry no obligation. If our number does not work for you, keep the list. We prepare them to earn the material order, and that is the whole arrangement.
What a quote binds
A quotation is an offer to supply on the terms and for the validity window stated on that quotation. Once that window passes, the numbers lapse. Lumber and engineered wood move with the market, and a quote that is weeks old is a historical document rather than a price.
Quantities
A takeoff is our reading of the drawings you sent. It is prepared carefully by estimators using professional takeoff software, and it remains an estimate of what the set calls for. You are responsible for reviewing the list against your drawings, your means and methods, and your waste factors before you order. If a sheet was missing, illegible or superseded, tell us and we will re-run the affected assemblies.
Revisions
Send the revision cloud and we re-run what it touches, mark what changed, and price the delta. Changes to scope after an order is placed are handled as a change order, not absorbed silently.
04 Prices shown on this site
Automated estimating figures are preliminary planning references. Your reviewed proposal identifies the agreed scope, quantities, pricing, delivery, tax, timing and validity date. Payment is based on that exact approved revision; subsequent changes require a new review.
- Market reference is a published retail benchmark captured for New England at build time. It varies by store, ZIP code, colour, brand and availability, and we never present it as a guaranteed competitor price.
- Retail, contractor and project tiers are our own reference levels, not a promise that your project lands on any particular one.
- "Starting at" on doors, windows and skylights means the base configuration. Size, style, glazing, grids, frame and jamb are configured at quote and change the price.
- Sales tax and delivery are shown separately in a project quote or online checkout. Listed product figures do not include them unless expressly stated.
Product photography is representative studio imagery and the technical drawings are generated from each product's specification line. Confirm sizes, grades and brands on your project quote rather than from a picture.
05 The automated estimator
The plan reader at /estimate is a beta feature. A model reads your sheets, our assembly rules count the materials, and the result is priced from our price book. Its output is an automated estimate, not a staff-issued quote.
What it is not
- It is not a quote. It is a planning-level figure.
- It is not for construction. The redrawn plan sheet is a vector redraw of what was measured, issued preliminary, and no one should build from it.
- The model can miss details or misread drawings. Ask the estimating team to review the resulting quantities and specifications before relying on them.
The parameter-based ballpark estimator models a simple rectangular building for preliminary budgeting. Its quantities depend on the dimensions and options entered; no accuracy percentage is guaranteed. Have the estimating team review your actual drawings before ordering.
Do not rely on either tool for bidding, ordering, permitting or structural decisions. Send the drawings and get the free human takeoff, which is the path we recommend in every case.
Beta limits
Free plan reviews are capped per user and per day. A failed read is refunded to the allowance. File storage and plan analysis have different limits: a file may upload successfully but require human review because its format, size or content cannot be processed by the model. Coverage information identifies selected or omitted pages when available; do not treat a partial read as a complete takeoff. We may change, pause or withdraw the beta feature.
06 Your plans and your rights in them
Your drawings stay yours. Sending them to us transfers no ownership.
By sending a set you confirm you have the right to send it, and you grant us a limited, non-exclusive licence to open, read, measure and copy it for one purpose: preparing your takeoff, quote and package, and supporting the resulting order. We do not publish your drawings, share them with other customers, or use them as marketing material.
If your set is under an NDA or a confidentiality obligation that the automated processing described in clause 05 would breach, do not use the automated estimator. Contact the estimating team about the restriction before sending the set.
07 We are not your engineer
We quote and supply what your structural drawings call for, and we will flag anything that looks off to us. Structural design, member sizing, connection design and code compliance stay with your engineer and architect of record.
Nothing on this site, in a takeoff, or in a conversation with our team is engineering, architectural or code advice, and none of it substitutes for a licensed professional stamping your drawings. Engineering and architectural services must be expressly identified in the agreed project scope.
08 Orders, deposits and delivery
National Lumber serves projects in Massachusetts, Rhode Island, Connecticut, New Hampshire, Maine and Vermont. Material fulfillment is by delivery only; the current material minimum is $200 before delivery and tax. Construction, installation, coordination and any other turnkey services are included only as expressly described in your approved project proposal.
The team confirms the project address, delivery charge, applicable tax, timing and scope before issuing your proposal. Open your private proposal link to review the approved total and conditions, then continue to secure payment. Payment is confirmed only after the payment provider verifies it. Your confirmed order includes a private tracking page.
Delivery timing is displayed during checkout when available and remains subject to product availability, order processing and site access. Enter accurate delivery and unloading details with your order. Products without a complete online configuration or a confirmed price cannot be purchased through checkout.
Payment is confirmed only after our system verifies it with Stripe. A browser return or a submitted list does not confirm payment. Payment and delivery progress are shown separately in your account. Stripe handles payment details and saved payment methods; our portal does not collect full card numbers or security codes.
Returns
Contact nationallumberri@gmail.com to request a return within 15 days after delivery. Eligible products must be in good condition and properly packaged. A 20% restocking fee applies. Special-order products are not returnable. Contact the team before sending materials back so eligibility and return arrangements can be confirmed.
Cancellations
Request cancellation within the first 24 hours after placing the order by contacting the team with your order reference. A request is subject to the order's processing, procurement and delivery stage; it does not automatically confirm cancellation or a refund. The team will confirm the outcome and any applicable costs.
Product warranties
Warranty coverage depends on the product and manufacturer. Ask the team for the warranty applicable to your selected materials. A warranty supplied for a specific brand does not extend to all products sold by National Lumber. These policies do not limit rights that apply under law.
09 Acceptable use
Use the site for its purpose. Do not:
- Scrape, bulk-download or systematically copy the catalog, the price book or the product pages.
- Automate requests against the estimate endpoint, or work around the quotas, App Check or rate limits protecting it.
- Upload malware, or files you have no right to send us.
- Probe, disrupt or attempt to gain unauthorised access to the site or its backing services.
- Republish our pricing as your own, or present our references as a competitor's prices.
We may block access that breaks these rules.
10 Our content and marks
The text, layout, drawings, photography and catalog data on this site belong to National Lumber & Building Materials Co. or are used with permission. You may read them, print them and quote them for your own project. You may not republish them commercially.
"National Lumber & Building Materials Co." and our mark are ours, with a trademark application pending at the USPTO. We are an independent Rhode Island corporation and are not affiliated with any other company operating under a similar name. Third-party brand names in the catalog belong to their owners and appear so you can identify the product.
11 Availability and beta features
We do not promise the site is always up. It may be unavailable for maintenance, for a provider outage, or without warning.
Features explicitly marked beta or preview may change, and clearly labeled examples are illustrative. Account projects, received requests, saved conversations and order records are operational records, not sample data. Uploaded plans reach private storage through the website; automated email is a notification channel and a delivery failure does not remove the saved request. If a submission fails, the interface does not confirm it as received.
12 Disclaimers and liability
The site and its estimating tools are provided as they are, without warranties of any kind, express or implied, to the fullest extent the law allows. We do not warrant that quantities produced by an automated tool are accurate, complete or fit for your project.
To the fullest extent permitted by law, National Lumber is not liable for indirect, incidental, special or consequential damages, or for lost profits, lost bids, delay costs or reworked material, arising from use of this site or reliance on a preliminary figure from it. Our total liability arising from your use of the site is limited to $100.
This clause limits liability for the website and its tools. It does not limit our obligations under an accepted quotation or supply contract, which are governed by those documents, and it does not exclude anything that cannot lawfully be excluded, including liability for fraud, or for death or personal injury caused by negligence.
13 Governing law
These terms are governed by the laws of the State of Rhode Island, without regard to conflict-of-laws rules. Disputes arising from them go to the state or federal courts sitting in Rhode Island, and both sides consent to that jurisdiction. If a court finds any clause unenforceable, the rest stands.
14 Changes and contact
When these terms change, the issue date and revision letter in the title block change with them. Continuing to use the site after a change means you accept the revised terms. A change here never alters a quotation already issued to you.
