Advantages of a Copper Clad Mantle:
At CBD our main product-line has been designing and fabricating custom exterior rain management products, so these copper clad mantles are especially good for exterior applications that would be subjected to the elements. Where varnished wood or other materials would not hold up nearly as well. Even longer lasting than concrete slabs.

These are also used for indoor application for a nice clean look that can resist scratches and the radiating heat better than any painted or lacquered wood surface. Also, soot can be scrubbed off with out worry of harming a delicate surface. Copper is also much more anti-microbial than any other surface, so other than dusting it off there is no cleaning required.

If you do not care for the patina look it may develop over time, it can be polished again and again without damaging the copper surface. A variety of chemicals can be applied to achieve a number of different looks in the patina. And start all over if you decide that you want a different look, or just bring it back to that new copper penny look again. It then can be waxed or given a thin lacquer coating to retain that look, but you would loose the anti-fungal advantage. It could even be painted, and later stripped off without harming the copper.

I made a special purchase of a large quantity of beech hardwood to use as a good sturdy substructure for these custom mantles. These boards are over 1" thick and range from 5" to 13.5" wide by 8' long.

Excess Heat to a Mantle:
A few clients have asked if a wood substructure is safe over a fireplace that may be subjected to high heat. That is a good question, which is a very important consideration.

Besides what building code and fire code would say on this subject, to think of this logically; if there was enough heat emissions from the fire place to start an exposed wood mantle on fire you would have a much bigger toxic polution problem that will need corrected right away: poor draw from a flue obstruction or downward draft. I cannot know your specific situation, but I have seen a lot of exposed wood mantles, and I am sure you could easily find thousands of photos of such on-line. So, I imagine this has not been a problem in most homes with a wood burning fireplace that is functioning propperly. A natural gas insert should be even safer, being a more regulated heat source.

The varnish coating is at more risk of being destroyed and possible catching on fire than the wood. The copper cover over a wood substructure can handle up to 2,000 degrees and would likely smother the oxygen needed for combustion around the wood hidden inside, so even if it were subjected to that much extreme heat and even direct flame contact it would be quite a bit safer than most any wood mantle.

Also, I know many people have nick-nacks place over their mantle that cannot withstand nearly that much heat without damage. It is also common to see a large portait photo, painting, or flat-screen TV mounted over a mantle, which would be highly vulnerable to such high heat. It could be possible that for some reason you have an unusually high heat coming out from within your fireplace. If so, that is a serious issue that needs to be corrected before using the fireplace again.

I may not be able to gurantee there could never be a problem, but I hope this helps resolve any concerns you might have on this issue.

Examples, Styles, & Price:
Below you will find several examples of the mantles we have built for clients over the last decade. Keep in mind you are not limited to just these styles shown. Custom work is our specialty. They are listed along with the price they had paid at that time, including the cost of a crate and freight charges when they are not local to the Portland Oregon area. This way you can get a good realistic idea of what we charge before you need to contact CBD for a quote. This is more information than you are likely to get on any other web site, so I hope you appreciate my transparency here.

When contacting me for a quote please be as specific as possible to let me know just what size and style you want, so I can calculate the cost for your unique project. There is no discount for just copying a previous project.

Size & Design:
are numerous ways to go about building a custom mantle for you as to the size and style taken into account, but this still needs a solid wood or concrete core inside to resist denting and give this a good solid feel.

This will also need a firm attachment, which is sturdy enough for an adult to sit on the mantle, so there is no risk of this becoming dislodged. I will help with the design of this mounting system that is also not too complicated.

For a more rustic look some clients have us add a patina and or texture the copper with a hammered look. as well as adding a string of copper domes to resemble large industrial rivets, as seen in steel bridge construction. The main benefit of a hammered copper surface is so that future dents and scratches are not nearly as noticeable. This is done before adhearing the copper to the wood substructure for a more rustic look at an added cost of $20 per square foot for each treatment: patina or hammered. The domes can be made different sizes and tend to run $3 each installed.

For sizing you would do well to form a temporary mantle to test fit in place to get a better feel for the size that would best suit your needs. This can be done with scrap wood or just cardboard box scraps cut and taped together to fit different sizes for sampling. Once we have built this in copper it is pretty much set, so anything you can do on your end to figure out the best size is a very important first step to your long term saticefaction. I would hate for you to get it mounted and not be happy with that size you had requested.


Sturdy Mounting:
It is very important to have worked out a sturdy attachment for any mantle, which is also not too complicated to install and change, along with a hidden from sight bracket, if possible. I will do my best to help you out with this design and even make you a wall brace to set this onto, but I will need to know what it is that we are attaching to, or what support there are behind the wall for anchoring the wall brace onto. You may need a studfinder to list the placements of your studs hidden behind the wall, so I can predrill the screw holes for you.

As for the cost; these will run between $100 to $300 per linear foot. This depends on the size, style, and if it will need a crate with truck freight to be shipped out of State from here in Oregon, so this cost can vary widely. We will need you to be as specific with these details for me to offer you a specific cost quote. A set of photos and description of where this is to go will also help, so I am not just working blind.

As to Adding a Polish or Patina Look:
Personally I rather like the look of new shiny copper, but aesthetics is very subjective. Even indoors copper will gradually turn a satin brown just from the humidity in the air and the oils from finger prints will make it spotty. Raw exposed copper is thought to be a living finish; in that it is ever changing. Most of the work we do is for exterior rain management products, so the finish of the copper is not much of an issue, since it will patina soon enough, but indoors this process is a great deal slower.

The copper we have access to is not polished, and will have tiny scratches in it, and perhaps a few small dents, as with anything hand-made, which cannot be made machine perfect. It is a lot of work to polish this copper to a mirror finish, which has not been one of our specialties, so I cannot guarantee the finish will meet your satisfaction. That said; you will need to be a bit flexible with us on this detail. Copper can be polished at any point of it's lifespan, so imperfections is something you will not be stuck with. As long as you are willing to have it worked over until it meets your satisfaction. That's just not a service we provide. Especially for out of State clients, which is the majority of our sales.

Numerous Clients have ask about having us hammer, color, or patina this copper for an antiqued rustic look and also hide any new scratches or dents that may occur. There are numerous chemical combinations to get different colored patinas, or copper can be heated up with a torch to get some interesting random rainbow colors on the copper surface, as seen in this photo.

If you want this desired look not to change it would then need to be covered up with a clear lacquer over it to retain that specific look. Although, the down side of this is how that soft plastic coating will get scratched up a lot easier than the harder copper surface. Also, it will eventually crack and peal over time or heat exposure from the fireplace in use. Making it look terrible. It also looses the advantage of the natural ability of raw copper to kill germs on contact.

After discussing the pros and cons of this our Clients often decided to forgo that costly option, as it may take numerous tries to get the desired look. Which I would need to charge for all that time required for each attemped patina, and repolishing to start over if you are not satisfied with that look you see in the photos I share with you.

If you are not local to us we will share progress photos of your project as we go, but as you know that may not properly represent how this may look in person. If we get the tone you like it can be waxed to retain that look, but that would need to be reapplied frequently. Finger prints will make the copper turn darker in a spotty manner, but that can also be a rustic charming look some Clients like. If at any point you decide you don't like that look it can be stripped and polished again to start over and find the look you like best, but this can be a long drawn out process requiring your personal attention and on-site inspection.

Although, keep in mind copper left untreated is 10X more anti-microbial than stainless steel or a plasic surface, so there is virtually no cleaning needed with raw copper. Without a lacquer you are not stuck with that one certain look. Here is a list of different chemicals used to make differnt colored patina:

An expensive PVD coating or gold gilding is the only type of good lasting scratch resistant coating I know of to retain the new look of copper or brass; as with the better door knobs. Although, large projects like this may cost more to coat than it costs to make and ship it. That runs about $100 per square foot for gold-leaf applied.

Most of the work we do is custom to order, so feel free to ask for any variation of the examples shown below, which shows the diversity of what can be done to build your needs and desires for this project.  Even if your needs are different than what is shown on these pages I am happy to help brainstorm solutions, design, and fabricate nearly anything you may want.

As you'll see most of my client are not local to us, so I do ship orders all across the Nation as well. Don't be shy and write me an e-mail to ask if we can help with your project.

Good afternoon. A few months ago you did a fireplace for us, which worked out great. Picture below.

I was wondering whether you can do a custom wall vent / wall register? I have three that I’d like to do.

Subject: I finally got the mantel installed this week
Date: Thu, 20 Oct 2016

Hi David,
I hope that everything is going well up in Oregon. After six months, my finish carpenter finally made it over here this week to install the mantel. I have attached a couple of photos.
My carpenter ended up using two pieces of L shaped heavy gauge steel to mount the mantel. He drilled two holes in the lower part of each L and bolted those to the studs on the sides. The upper part of the L acted as a sort of ledge for the mantel. He cut two grooves in the copper on the back of the mantel, and we just slid the mantel into place. It is not going anywhere.

My wife likes it, and it seems to deflect the fireplace heat as we had hoped which will protect the TV. I might move the television up an inch or two for better spacing, but we will see over the next couple of weeks.

Thanks for making the mantel. It is a nice looking piece.

We love our mantle. I will be glad to send you some pictures. David was great to work with and we have received several compliments on the mantle. There was a small mark from shipping but I actually had forgotten about it until David mentioned it. I will set a reminder on my phone to send you some pictures later tonight. We are going to the state fair after work, but I'll get you something when we get home. I'll send some photos showing the mantle close up and some showing it in the room. Is there anything else you would like to see? Thanks! Steve
