We "refreshed" our kitchen about 6 years ago by adding a set of cabinets (upper/lower) on a blank wall, changing the countertops, putting in a new wall oven & stovetop & laying down a linoleum floor.
In order to match the cabinets to our existing, we decided to paint them, & hired a family friend to do it for us. They removed the cabinet doors & hardware, painted the boxes & doors, & put them back on with updated hardware. They look fantastic! (btw, the doors of the new cabinets & our existing were the same, so the style matched already)
We went with a dusty cocoa wall color, & painted the cabinets a creamy white. Our appliances are white, & the linoleum & countertops matched the color scheme. The entire kitchen is bright & inviting as a result.
Couple things I would do differently, hindsight being what it is.
1. The linoleum floor hasn't held up well - we didn't get the most expensive, stupid mistake on our part. So we will be redoing that.
2. The base cabinets are also painted a creamy white. With 5 dogs coming in & out of the backyard through the kitchen, you can just imagine what the base cabinets look like after all the muddy tails have attacked them!!
3. The cabinet doors we had were just a basic piece of wood - no moulding or routing for dimension. Considering they were circa 1965, the paint helped, but they aren't as "updated" looking as they could be.
Our costs, as best I can remember:
Extra cabinets for blank wall (8' upper & lower) - Craigslist $200
Paint - about $200 for the walls & cabinets. We went with a high-grade semi-gloss on the cabinets, to withstand wear. We probably overspent on paint, I know we have a few cans in the basement that didn't get fully used
Linoleum - I think $250 for a 12x12 roll of mid-grade gluedown, & cut to size.
Oven & Stovetop - Craigslist finds! Oven was used, for $200 & stovetop (5 burner) was new for $50, but we needed to buy the flat difuser for each of the gas burners at)
Counters - $150 (we bought the stock 8' laminate counters in a pattern we didn't hate & cut to size)
Sink - (enamel cast iron) also a Craigslist find, used in great condition for $45
Faucet - New, $50
Cabinet Hardware - we found a nice brushed nickel design on sale @ Menards, even still we spent $150!
All told, kitchen refresh totalled under $1500
The shopping we did was at Menards, which is comparable to a Lowe's or Home Depot (maybe even slightly cheaper cost)
Now, prior to buying the extra cabinets & doing all this work, we did price out what it would cost to have our cabinets refaced or replaced. Century 21 came & gave a refacing quote (keep your existing cabinets, they will recover them to look like new) - $12000. I am NOT joking! I think that included adding the extra cabinets to the blank wall... but still!! (I have heart palpitations just thinking about that much cost)
To replace our cabinets with mid-grade cabinets bought @ Menards & install ourselves I think priced between $2500 - $4500, depending on style & options.
Going forward, this year we have decided to pull up the linoleum & lay tile down. This will involve laying an additional subfloor of plywood (the reason we didn't go this route 6 years ago).
We are also going to buy new cabinet doors with some detail to them. Priced out, they are very affordable @ Cabinet Door World, unfinished & ready for painting! (http://www.cabinetdoorworld.com)
Finally, we are going to repaint the base cabinets to help hide the muddy tail-prints. Keeping with our color scheme, we are going to use a rich brown, making our kitchen 3-tone: Dusty Cocoa for the walls, Creamy White for the upper cabinets, Dark Chocolate for the base cabinets. (tile on the floor will likely be a mid-way brown, not as dark as the base cabinets)
We are hoping to find the tile we like at HOBO (Home Owner Buyers Outlet) for under $500, grab the plywood & paint @ Menards, & all told, be done for under $1000. Labor, we will do ourselves (my husband is quite the handyman)
I know this was a bit more information than you were looking for, but I thought it would be helpful to include other "updates" & associated costs... 5-7 years is a good amount of time to spend enjoying your kitchen, & sometimes updating one area really requires updating another to get the full benefit (such as the hardware to our painted cabinets).
Wishing you the best of luck, whether you DIY or purchase supplies & hire a handyman/contractor to provide the labor. T.
ETA: As Theresa mentions below, make sure you follow proper procedures to having the cabinets painted, so that they are durable. Talk to the salesperson when you buy the paint to make sure you get a brand & type that will hold up to the abuses of cabinet doors. I love the semi-gloss we got, as it wipes easily with a wet cloth to clean up.
Also, depending on how much dimensional detail your existing doors have, there may be more work involved in sanding it down prior to priming/painting. And, you may need to rehang the doors differently, or sand down the inside edges, so that the doors still close flush after the coat of primer/paint/etc.
If you have nice doors & wouldn't mind keeping the wood look, there are also stains available that do a nice job. Some apply like a paint, some require a full sand & restaining. Friends of ours just updated the woodwork in their house using some type of 'miracle' that refreshes existing stainwork. Again, talk to the salesfolks @ your local hardware store.
Just make sure you get someone knowledgeable! (sometimes, going to a mom & pop store will get you someone who knows exactly what you need, vs. the "I know what brands we carry, but it's up to you to buy the right product" floor staff @ the big box stores)
