When your deck or patio is complete, most contractors will give you a written invoice that details the completed work.

A valid invoice will include:

• The contractoris name, physical address and license number.
• A list of all services performed.
• The total cost for supplies, including the amount due for labor.
• Any applicable warrantees or guarantees provided by manufacturers or the company.
• An itemized list of all the building supplies purchased.

It is wise to compare the completed work with the written invoice. Ask your contractor to walk through the deck or patio with you and show you the work.

Check the work with the invoice. During the walk-through, ask if there are any special instructions for maintaining your new deck or patio. If you have any questions about the work or materials used to build the deck or patio, now is the time to ask.

Most good deck and patio contractors offer some time of warranty on the deck or patio and the materials that are used to build it. Ask that the details of the warranty be provided to you in writing.

For your protection, this information should include:

• The patio and deck contractor’s name and physical address.
• What products and parts of the deck or patio are covered. This should also include whether the contractor will replace or repair your deck or patio in the event of a product failure.
• Your responsibility if you place a warranty claim (i.e., if you have to pay for labor or materials, or if you are required to pay a prorated amount).
• Terms, limitations and exclusions on the materials and workmanship.
• If the new deck and patio warranties are transferable to the new owner if you sell your home.

Eco-Friendly Vinyl and Composite Patios and Decks
Many homeowners are interested in building decks with green materials. There is a variety of materials that meets the standards of these homeowners. Probably the most eco-friendly material for decks is wood, but there are also many composites that are made up of a high percentage of recycled materials. Vinyl is also available that meets this criteria.

Vinyl Decks and Patio Materials
Vinyl is a durable option for decks. It is lower in maintenance than wood but does give more of a contemporary look. Its appearance is more man-made. One of its greatest benefits is that it does not warp or rot and it is not subject to mold. Most vinyl decking comes with a lifetime warranty.

Untreated Softwood
Untreated softwood is inexpensive. Softwoods include pine and fir. Although it is inexpensive, it will be necessary to treat it every two years or so with stain, paint or sealant. A problem with untreated softwood is that it is susceptible termites.

Solid Composite Wood Decks and Patios</b

Composite wood gives you the look of natural wood, however the maintenance is much easier. A composite wood deck is made of a blend of wood fiber with plastic. This type of wood comes in different colors and it is very durable. Solid composite wood decks expand and contract as the weather fluctuates. The plastic gives this deck more durability.

Pressure Treated Lumber
Many consider this a very affordable option. It does require some maintenance and although it is pressure treated, it needs to be taken care of. With regular maintenance, this decking will last and look great.

Tropical Lumber
Tropical lumber or exotic imports are considered heavy hardwoods. This can include mahogany or ipe. This lumber is resistant to insects and damage from weather.

Aluminum Decks
Aluminum decking is very low in maintenance however it is not inexpensive. It is recyclable. One of its positive aspects is that it is almost indestructable and even fireproof. Aluminum may cost several times more than exotic lumber. Homeowners choose it because it is so easy to take care of.

Cedar Decks and Redwood Decks
These woods are very popular because they are naturally beautiful. They do require regular maintenance and, unfortunately, they are liable to damage from insects and the weather. With proper maintenance such as staining and sealing, this decking can last for many years.

Natural Wood Decks and Patios
This is probably the most popular material for building a deck. It is naturally beautiful and also quite affordable. While it is cheaper than composite material, the maintenance requirements for wood are greater than for composite. Another reason homeowners choose wood is that it is more versatile and can be stained a different color.

Hollow Composite Wood
Hollow composite wood does not have quite the natural look of wood as the solid composite. You will also find that it is less durable; however, hollow composite wood costs less than solid composite wood. Hollow composite wood decking is stiffer than solid composite wood and allows you to run wires for lighting or speakers.

Q: Do I need a permit to build a deck?
A: In most cities a permit is required because a deck is considered structural. This means it carries weight other than itself – the weight of a person. Because of the way some decks are built – high off of the ground – they require structural building to transfer the weight of the load to the ground.

Q: What happens if I build without a permit?
A: We highly recommend that you do not do it. Getting a permit isn’t that difficult and it will save you the hassle of any difficulties that arise from not having a permit. Without a permit, you could be fined or not able to sell your house until the permits are obtained.

Q: Is it necessary to maintain my wood deck?
A: If you want your deck to look good and keep it from rotting or splitting, then, yes, you need to maintain your wood deck. Regular maintenance will keep your deck from showing signs of deterioration from the water or sun. In time, without maintenance it will eventually rot or the wood will split.

Q: When should I seal my wood deck?

• After your wood deck is completed, wait six to eight weeks to seal it. Sealing your wood deck will keep it from discoloring and it will also keep the wood from splintering.
• All wood decks need to be cleaned. Power washers do not damage wood when they are used properly. However, power washing decks and patios may raise the grain of the wood. Before you seal your deck, you will need to sand this down.
• Seals are a protection for wood that works by penetrating the wood fibers. This slows the water absorption causing the water to evaporate before it is absorbed.
• Many types of sealant are an oil-based covering that protects wood. It not only protects but improves the appearance of decks and patios. Deck sealing lasts for several years depending on weather conditions.
