FAQ

What types of products does FixTimber offer?

FixTimber offers supplies for repairing, reinforcing, sealing, weatherproofing, preparing, and finishing wood-frame homes. Our collections include wood repair compounds, adhesives, fasteners, structural hardware, exterior hardware, weatherproofing materials, finishing products, and repair tools.

How do I know whether a product is suitable for my project?

Review the product description, intended application, dimensions, materials, compatibility information, and installation requirements before ordering. If you are uncertain, contact us with details about your project and the product you are considering.

Are your products suitable for outdoor use?

Some products are designed for exterior applications, while others are intended only for indoor or protected areas. Check the individual product page for information about weather resistance, moisture exposure, temperature limits, and suitable surfaces.

Can I use these products for structural repairs?

Certain fasteners and connectors may be intended for structural applications, but suitability depends on the building design, load requirements, local codes, and installation method. Structural repairs should be evaluated and completed by a qualified professional when appropriate

Do products include installation instructions?

Instructions may be included with certain products or provided on their product pages. Instructions and accessories vary by manufacturer. Always follow the supplied directions and applicable safety requirements

How can I choose the correct size of hardware or fastener?

Measure the relevant lumber, opening, connection, or existing component carefully. Compare those measurements with the dimensions and specifications shown on the product page. Do not select structural hardware based on appearance alone.

Will product colors and wood finishes look exactly like the images?

Colors may appear different because of lighting, screen settings, wood species, surface preparation, and application method. Test stains, fillers, waxes, oils, and coatings on a small inconspicuous area before completing the entire project

Processing and delivery times depend on the product, destination, carrier, and current order volume. Estimated delivery information may be displayed during checkout or provided after the order is processed. Please review our Shipping & Delivery Policy for additional details.
